Add more status checks for binaries

Summary:
Expands on D7488, which looks way better than the config checks. I'm leaving the config checks for now, but maybe we should just get rid of them? This advice is delivered in a far more timely way.

  - Check for normal VCS binaries too.
  - Link to `environment.append-paths`.
  - Get rid of untranslated names (I think they're probably not too useful?)

Test Plan: See screenshots.
