This is a stacked PR based on #216244 , which will be a standalone
commit that
renames *.rst -> *.md before this PR lands for history preservation
purposes.
This PR has two commits:
- One that is the raw output of rst2myst
- A cleanup commit using LLMs and prompting
I validated the output by rendering the web page and looking at pixel
diffs, and all the diffs appear to be bug fixes. I don't yet have a way
to publish that artifact, but I'm working on it.
