docs.github.com has a markdown API available

docs.github.com now has an API available to get Markdown versions of every page of the site, example:

https://docs.github.com/api/article/body?pathname=/en/rest/activity/events&apiVersion=2026-03-10

You can also do `.md` extension or request with content-type header to get the markdown version instead.

Not sure if anything is still depending on this repo but we would prefer folks use the API if possible.
