Update plugin docs

[daun]

• Sync current plugin readmes and plugin pages on docs site
• Add a simple npm script for downloading plugin readmes into the docs site
  • This still needs manual review, but avoids lots of unnecessary labor

Looks great!!

I've just tested it locally and the process already is pretty painless. Keeping the front matter automatically would still be an improvement, I think.

Added your proposed changes. Keeping the frontmatter would indeed be great, but would be much more complicated then the 'dumb' version used here. Not too motivated to keep exploring here 🤡

I have done some refactoring on the script, see above. I hope it's ok that I'm chiming in with own commits to the PR :)

...I noticed that http.get doesn't error if the response.statusCode is 404, that's why I added the check for it. Otherwise, the script would create a file for the non-existing plugin with contents of "404: Not Found".

Perfect! Feel free to review and merge.
