Observations:

• All of the "RuntimeError: tk.h version (8.6) doesn't match libtk.a version (8.5)" happens in tests that are decorated with @_isolated_tk_test(). We have a couple more uses of the decorator, which also have @pytest.mark.backend('TkAgg', skip_on_importerror=True) and thus don't fail.

Proposed fix

See upstream issue actions/setup-python#402

This was "fixed" by #23095, and then really fixed by upstream, which was confirmed by the revert in #23355.
