Brian Lyles c282eba2d5 rebase: update --empty=ask to --empty=stop
When git-am(1) got its own `--empty` option in 7c096b8d61 (am: support
--empty=<option> to handle empty patches, 2021-12-09), `stop` was used
instead of `ask`. `stop` is a more accurate term for describing what
really happens, and consistency is good.

Update git-rebase(1) to also use `stop`, while keeping `ask` as a
deprecated synonym. Update the tests to primarily use `stop`, but also
ensure that `ask` is still allowed.

In a future commit, we'll be adding a new `--empty` option for
git-cherry-pick(1) as well, making the consistency even more relevant.
