[WalkQuackBack]

Implement versioning into the Standard Library.

Checklist before merging:

• Update documentation to reflect new structure
• Document introduction of new library updates by Userstyles Staff

Ah hmm. I think the imports are failing because we aren't replacing them in the lib content itself. Will try to think of a fix.

To clarify for myself - the imports of userstyles.catppuccin.com in the lib shim aren't being replaced because we are only patching URLs in the main userstyle content itself. The better approach would be to intercept fetch requests to that host and return responses to the local file system, but I'm having trouble implementing that in Deno.

This is looking good to me with a new documentation structure and updated for v1, v1 moved from lib/lib.less to lib/std/v1.less, and the linting has been fixed to match the local repository instead of the remote website in #2292.

Made some minor edits and moved some links around, but overall looks good! Thanks for the work documenting all of this ;)
