The problem is that bugfix release PRs do not result in a modification of any of the files that would trigger a test suite run.

pip/.github/workflows/ci.yml

Lines 52 to 57 in 457ca6e

	tests:
	# Anything that's touching code-related stuff
	- ".github/workflows/ci.yml"
	- "src/**"
	- "tests/**"
	- "noxfile.py"

For 24.1, the PR does bump the version number which was then detected by the determine-changes job.

For 24.1.2 (and 24.1.1), while the version number is bumped temporarily, it's reverted to the original version on main in the same PR, resulting in no net change in src/pip/_internal/__init__.py.

To work around this, perhaps it would be best to also trigger a test suite run when NEWS.rst is modified or when files are deleted from news/ (either of which typically only happens when cutting a new release).
