[PATCH 1/2] submodule documentation: add options to the subcommand

[Stefan Beller <sbeller@google.com>]

When reading up on a subcommand of `gi submodule`, it is convenient
to have its options nearby and not just at the top of the man page.
Add the options to each subcommand.

While at it, also document the `--checkout` option for `update`.

  This mini series applies to master, there no other patches in flight
  that touch Documentation/git-submodules.txt except
  sb/submodule-default-paths, which we are holding back currently.
  
  Thanks,
  Stefan
