SUMMARY

Follow-up to #12985. Heavy integration targets are grouped by the backend service they need, so that each backend can be tested on its own in GitHub Actions:

• heavy targets use a heavy/<backend> alias instead of heavy (rundeck now has heavy/rundeck); heavy/ still selects all of them;
• each backend has its own session in antsibull-nox.toml, tagged heavy-<backend>, replacing the session in noxfile.py; nox -Re ansible-test-integration-heavy still runs all of them;
• each backend has its own manually triggered workflow, nox-heavy-<backend>, starting with nox-heavy-rundeck; the regular nox workflow excludes the heavy tag;
• the aliases extra sanity check fails when a heavy/<backend> alias has no tagged session or no workflow.

GitLab (#13005) is meant to be added as another backend.

Thanks again for working on this!

Since tomllib has been around since Python 3.11, let's remove the try and tomli fallback. This will also fix the mypy errors.

Suggested change

	def get_heavy_targets():
	def get_heavy_targets() -> tuple[set[str], bool]:

Also try to see whether this "just works". If not, I can fix it in a follow-up.

Suggested change

	def main():
	def main() -> None:

We could also try to have a single workflow, where you have to select from a dropdown which backend to use. That would avoid having to add more of these files in the future. I can work on that in a follow-up.
