[Request] Wrap markdown lines

[AngelOnFira]

Motivation

When editing markdown files, it's nice if they wrap at ~80 characters, so it's a bit more readable. We do this for the Rust Gamedev Newsletter (example).

It's quite subjective, but it does make it nicer for others to edit I think :)

I wish there is a cmd tool which we can use offline and on CI, then we can properly enforce it!

I think we should avoid long line. Wrapping isn't ideal, could you list a few pages with long code snippet?
