doc: Remove unnecessary link to VC redist, update md lint rules (#7926)

Terminal ships with this dependency embedded, and it is not required that you install it separately. Since the link is broken, let's just remove it entirely.

* [x] fixes #7889 
* [x] related to #7917 (comment)
* [x] I work here
* [x] is a docs update

Additionally, update the markdown linter rules in the wake of #7637, because apparently that was never actually applied to any files, so now the onus is on the first person to touch any of our markdown files.
