Switch from Prettier to Rumdl for Markdown formatting (#7423)

Rumdl already appears to have _significantly_ fewer bugs than prettier,
and a solid LSP for editor integration.

The tool is: https://github.com/rvben/rumdl/

I've separated out the change across three commits for easier review.

The configuration tries to match the existing formatting, the changes to
the all the files are to correct issues found by the new tool.

split up pull requests:
1. Ensure that each pull request builds and passes any tests cleanly when you
request review and when it lands. This will ensure bisection and continuous
integration can effectively process them.

right": not too big, not too small. You don't want to separate a pattern of
tightly related changes into separate requests when they're easier to review
as a set or batch, and you don't want to bundle unrelated changes together.
Typically you should try to keep the pull request as small as you can without
breaking apart tightly coupled changes. However, listen to your code reviewer
if they ask to split things up or combine them.
