Remove a mention of "rvm help" that is unnecessary

This sentence doesn't really make much sense with "rvm help mount" at
the end. None of the other actions explicitly mention "rvm help" in
their short descriptions because there's already a mention at the top
that "rvm help action-name" may provide more information, and "mount"
appears in the list of commands available with rvm help.
Fixes #2571. Escape the . in the regex that removes ".md" from help filenames

This was causing an issue with the file "gemdir.md"; it caused "gir.md"
to appear in the list of commands that have help available instead of
"gemdir".
Anchor .md filename replacement to the end of the filename

Improves the fix for #2571. Makes sure that we only remove ".md" in a
help filename if it's at the end.

I tried running `rvm build` in order to document more what it does, and
it's an unrecognized command. So I get to delete more!
