[PATCH v2] doc: git-rebase: Update incompatible options

[Omri Sarig <omri.sarig13@gmail.com>]

Several options in the rebase man page link to the "INCOMPATIBLE
OPTIONS" section when the option is no-longer incompatible with any
other option.

- Commit 1a66d8c6f6 (rebase: remove --allow-empty-message from
  incompatible opts, 2023-01-25) removed "--allow-empty-message" from
  the INCOMPATIBLE OPTIONS section, but did not remove the link to that
  section from the option description.
- Commit a74b35081c (rebase: drop support for `--preserve-merges`,
  2021-09-07) removed the `--preserve-merges` option from rebase, which
  removes all incompatbiilty references to `--ignore-date,
  --reset-author-date` and `--signoff`.

Additionally, `--onto` doesn't link to the INCOMPATIBLE OPTIONS section, even
though it is incompatible with `--keep-base`.

Update the description of these option, to have correct references to
the INCOMPATIBLE OPTIONS section.

Changes in V2:
- Update commit message per the review comments from Phillip (Thanks for the
  review!).
- Add `--onto` to INCOMPATIEBLE OPTIONS.

I was not sure if both adding INCOMPATIBLE OPTIONS (--onto) and removing them
(the other flags) belong in the same commit, or in 2 separate commits. These
changes felt small enough to me to not require a second commit, but please let
me know if it's preferred. I'll happily send a new patch where these changes
are split across different commits.
