Done now.

>     2. You removed the changed CI trigger path again (clang/tests/bindings... or sth in libclang-python-tests.yml, can't check rn since I'm on mobile). I only noticed after merging yesterday, please add that one back in so the CI id triggered also when the tests in their new location are changed

Right, I accidentally reverted all changes to `libclang-python-tests.yml` instead of just the new `run:` statement.  Fixed now.
