command-list: mention git-credential-* helpers

These commands were never added to the command-list. Adding
them makes "make check-docs" run without complaint.
While we're at it, let's capitalize the first letter of
their one-line summaries to match the rest of the git
manpages.

The credential-cache--daemon command is somewhat special. It
is already ignored by check-docs because it contains a "--",
marking it as a non-interesting implementation detail. It
is, in fact, documented, but since the documentation
basically just redirects you to a more appropriate command
anyway, let's explicitly omit it so it is not mentioned in
git(1).
