Add save svg-badge directly to gist

This adds the posibility of saving an SVG badge generated by the same shields.io dirictly to the gist. Instead of prepering a JSON file to be sent to their service, we use their library directly, which outputs an SVG file that we can save to the user’s gist. Filenames ending in `.svg` will use this library automatically. Additionally there is a major refactoring where the older `node:http` library has been swapped out for `fetch`. Also swap from node 16 to node 20 fixes #24

+# Changelog
+
+## 3.3.1
+
+- Improve font measuring in for-the-badge and social styles
+- Make for-the-badge letter spacing more predictable
+
+## 3.3.0
+
+- Readability improvements: a dark font color is automatically used when the badge's background is too light. For example: ![](https://img.shields.io/badge/hello-world-white)
+- Better CSS color compliance: thanks to a switch from _is-css-color_ to _[css-color-converter](https://www.npmjs.com/package/css-color-converter)_, you can use a wider range of color formats from the latest CSS specification, for example `rgb(0 255 0)`
+- Less dependencies: _badge-maker_ no longer depends on _camelcase_
+
+## 3.2.0
+
+- Accessibility improvements: Help users of assistive technologies to read the badges when used inline
+
+## 3.1.0
+
+- Add TypeScript definitions
+
+## 3.0.1
+
+- Fix missing dependency
+
+## 3.0.0
+
+### Breaking Changes
+
+- Dropped support for node < 10
+- Package name has changed to `badge-maker` and moved to https://www.npmjs.com/package/badge-maker
+- `BadgeFactory` class is removed and replaced by `makeBadge()` function.
+- Deprecated parameters have been removed. In version 2.2.0 the `colorA`, `colorB` and `colorscheme` params were deprecated. In version 3.0.0 these have been removed.
+- Only SVG output format is now provided. JSON format has been dropped and the `format` key has been removed.
+- The `text` array has been replaced by `label` and `message` keys.
+- The `template` key has been renamed `style`.
+  To upgrade from v2.1.1, change your code from:
+  ```js
+  const { BadgeFactory } = require('gh-badges')
+  const bf = new BadgeFactory()
+  const svg = bf.create({
+    text: ['build', 'passed'],
+    format: 'svg',
+    template: 'flat-square',
+  })
+  ```
+  to:
+  ```js
+  const { makeBadge } = require('badge-maker')
+  const svg = makeBadge({
+    label: 'build',
+    message: 'passed',
+    style: 'flat-square',
+  })
+  ```
+- `ValidationError` had been added and inputs are now validated. In previous releases, invalid inputs would be discarded and replaced with defaults. For example, in 2.2.1
+  ```js
+  const { BadgeFactory } = require('gh-badges')
+  const bf = new BadgeFactory()
+  const svg = bf.create({
+    text: ['build', 'passed'],
+    template: 'some invalid value',
+  })
+  ```
+  would generate an SVG badge. In version >=3
+  ```js
+  const { makeBadge } = require('badge-maker')
+  const svg = makeBadge({
+    label: 'build',
+    message: 'passed',
+    style: 'some invalid value',
+  })
+  ```
+  will throw a `ValidationError`.
+- Raster support has been removed from the CLI. It will now only output SVG. On the console, the output of `badge` can be piped to a utility like [imagemagick](https://imagemagick.org/script/command-line-processing.php). If you were previously using
+  ```sh
+  badge build passed :green .gif
+  ```
+  this could be replaced by
+  ```sh
+  badge build passed :green | magick svg:- gif:-
+  ```
+
+### Security
+
+- Removed dependency on doT library which has known vulnerabilities.
+
+## 2.2.1 - 2019-05-30
+
+### Fixes
+
+- Escape logos to prevent XSS vulnerability
+- Update docblock for BadgeFactory.create()
+
+## 2.2.0 - 2019-05-29
+
+### Deprecations
+
+- `labelColor` and `color` are now the recommended attribute names for label color and message color.
+
+  - `colorA` (now an alias for `labelColor`),
+  - `colorB` (now an alias for `color`) and
+  - `colorscheme` (now an alias for `color`)
+
+  are now deprecated and will be removed in some future release.
+
+### New Features
+
+- Semantic color aliases. Add support for:
+  - ![success](https://img.shields.io/badge/success-success.svg)
+  - ![important](https://img.shields.io/badge/important-important.svg)
+  - ![critical](https://img.shields.io/badge/critical-critical.svg)
+  - ![informational](https://img.shields.io/badge/informational-informational.svg)
+  - ![inactive](https://img.shields.io/badge/inactive-inactive.svg)
+- Add directory field to package.json (to help tools find this package in the repo)
+
+### Bug Fixes
+
+- Prevent bad letter spacing when whitespace surrounds badge text
+
+### Dependencies
+
+- Bump anafanafo
+- Use caret instead of tilde for dependencies
+
+### Internals
+
+- Generate JSON badges without using a template
+- Refactoring
+- Testing improvements
+
+### Node support
+
+- Declare support for all currently maintained Node versions
+- Explicitly test on all supported versions
+
+## 2.1.0 - 2018-11-18
+
+gh-badges v2.1.0 implements a new text width measurer which uses a lookup table, removing the dependency
+on PDFKit. It is no longer necessary to provide a local copy of Verdana for accurate text width computation.
+
+As such, the `fontPath` and `precomputeWidths` parameters are now deprecated. The recommended call to create an instance of `BadgeFactory` is now
+
+```js
+const bf = new BadgeFactory()
+```
+
+For backwards compatibility you can still construct an instance of `BadgeFactory` with a call like
+
+```js
+const bf = new BadgeFactory({
+  fontPath: '/path/to/Verdana.ttf',
+  precomputeWidths: true,
+})
+```
+
+However, the function will issue a warning.
+
+To clear the warning, change the code to:
+
+```js
+const bf = new BadgeFactory()
+```
+
+These arguments will be removed in a future release.
+
+To upgrade from v1.3.0, change your code from:
+
+```js
+const badge = require('gh-badges')
+
+const format = {
+  text: ['build', 'passed'],
+  colorscheme: 'green',
+  template: 'flat',
+}
+
+badge.loadFont('/path/to/Verdana.ttf', err => {
+  badge(format, (svg, err) => {
+    // svg is a string containing your badge
+  })
+})
+```
+
+to:
+
+```js
+const { BadgeFactory } = require('gh-badges')
+
+const bf = new BadgeFactory()
+
+const format = {
+  text: ['build', 'passed'],
+  colorscheme: 'green',
+  template: 'flat',
+}
+
+const svg = bf.create(format)
+```
+
+### Other changes in this release:
+
+- Remove unnecessary dependencies
+- Documentation improvements
+
+## 2.0.0 - 2018-11-09
+
+gh-badges v2.0.0 declares a new public interface which is synchronous.
+If your version 1.3.0 code looked like this:
+
+```js
+const badge = require('gh-badges')
+
+const format = {
+  text: ['build', 'passed'],
+  colorscheme: 'green',
+  template: 'flat',
+}
+
+badge.loadFont('/path/to/Verdana.ttf', err => {
+  badge(format, (svg, err) => {
+    // svg is a string containing your badge
+  })
+})
+```
+
+To upgrade to version 2.0.0, refactor you code to:
+
+```js
+const { BadgeFactory } = require('gh-badges')
+
+const bf = new BadgeFactory({ fontPath: '/path/to/Verdana.ttf' })
+
+const format = {
+  text: ['build', 'passed'],
+  colorscheme: 'green',
+  template: 'flat',
+}
+
+const svg = bf.create(format)
+```
+
+You can generate badges without a copy of Verdana, however font width computation is approximate and badges may be distorted.
+
+```js
+const bf = new BadgeFactory({ fallbackFontPath: 'Helvetica' })
+```
+
+## 1.3.0 - 2016-09-07
+
+Add support for optionally specifying the path to `Verdana.ttf`. In earlier versions, the file needed to be in the directory containing Shields.
+
+Without font path:
+
+```js
+const badge = require('gh-badges')
+
+badge({ text: ['build', 'passed'], colorscheme: 'green' }, (svg, err) => {
+  // svg is a string containing your badge
+})
+```
+
+With font path:
+
+```js
+const badge = require('gh-badges')
+
+// Optional step, to have accurate text width computation.
+badge.loadFont('/path/to/Verdana.ttf', err => {
+  badge(
+    { text: ['build', 'passed'], colorscheme: 'green', template: 'flat' },
+    (svg, err) => {
+      // svg is a string containing your badge
+    }
+  )
+})
+```

+
+For these and/or other purposes and motivations, and without any expectation

+
+- ![][success]
+- ![][important]
+- ![][critical]
+- ![][informational]
+- ![][inactive] – the default `color`
+
+2. A three- or six-character hex color, optionally prefixed with `#`:

+
+## Raster Formats
+
+Conversion to raster formats is no longer directly supported. In javascript
+code, SVG badges can be converted to raster formats using a library like
+[gm](https://www.npmjs.com/package/gm). On the console, the output of `badge`
+can be piped to a utility like
+[imagemagick](https://imagemagick.org/script/command-line-processing.php)
+e.g: `badge build passed :green | magick svg:- gif:-`.
