This is a bit rough, but i did that while trying to figure out if there would 
be a good way to do
pre commit checks on RsT files.

Recommonmark has been deprecated, then archived last year. This was tracked by: 
https://github.com/llvm/llvm-iwg/issues/30

https://github.com/readthedocs/recommonmark

Before merging that we would have to update the bots, which I'm not in a good 
position to do, so feel free to take over!
