fix(commit): resolve 'always_signoff' configuration and '-s' CLI issues

[AdrianDC]

Description

The always_signoff configuration or the CLI -s argument fail upon git commit call
due to the passed syntax being git commit -- -s rather than git commit -s.

The -- is needed only on the commitizen CLI, and if no git argument is passed, the -- should not be forced.

signoff mechanic is deprecated, please use cz commit -- -s instead.
fatal: /tmp/...: '/tmp/... is outside repository at '...'

Tested with the python:3.12 Docker image:

docker run -i --rm --entrypoint bash python:3.12 <<EOF
{
  git clone -b signoff https://github.com/AdrianDC/commitizen.git /tmp/commitizen
  cd /tmp/commitizen/
  pip install poetry
  poetry install
  ./scripts/format
  ./scripts/test
}

Overall, looks good! just left one minor nitpick

Just noticed we haven't marked -s as deprecated yet. We should probably do that. Would it be possible for you to include that in this PR? Thanks!

I'd actually be against deprecating -s, given it's the most used parameter after -m since years in our use cases,
and I'd like to get a good adoption rate for either commitizen's cz c -s or git's git commit -s with my hooks.

Also, the always_signoff configuration I fixed in the first place through this MR requires this source code anyways.

---

If you're interested in my implementations of pre-commit + commitizen + prepare-commit-msg hooks,
feel free to check : https://radiandevcore.gitlab.io/tools/pre-commit-crocodile/commitizen/#configurations-for-commitizen
and the almost-auto-derived specifications : https://radiandevcore.gitlab.io/tools/pre-commit-crocodile/commits/

Initially meant to centralize the development features of my GitLab and Python related tools,
it grew quickly into an automated adoption tool for pre-commit and my commitizen configurations.

I will then deploy the configurations progressively on our internal projects (simply pre-commit-crocodile --configure)
and my developers will be able to use pre-commit-crocodile --enable easily on a day to day basis.

I'll probably use git commit -s on my side, especially with my automated type(scope): evaluators,
and let developers prefer to use cz commit depending on their personal feelings,
both giving a very similar result + same validation, and the CI/CD job component checks all commits either way.

My thought on whether to keep these "commonly used" arguments is detailed #1217 (comment). let's keep the discussion in one place 🙂

Thanks !

Fine, reworking the commits series tomorrow.

[AdrianDC]

Reimplemented as discussed, documentations updated and tests too.

Deprecation commit on top of this MR pushed for v4 on MR #1221.

Understood the test_commit_command_shows_description_when_use_help_option failures I couldn't see locally,
the test is restricted to Python 3.13, but the python:3.13.0rc1 image fails at poetry install for now.

Hi @AdrianDC , just a head up. I'm aware of these changes, but I am overwhelmed these days. I'll try my best to take a look ASAP.

[AdrianDC]

No worries @Lee-W , same here since 1+ year, only had time to work on my GitLab related tools the last weeks.

For the time being, my developers and pre-commit-crocodile users use the prerelease branch anyways,
until all commits are upstreamed, hence no rush : https://github.com/AdrianDC/commitizen/commits/prerelease/

(Tested the sync fork feature of GitHub, but it creates a merge commit rather than rebase, sad...)
