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
