Description: This PR updates the cmath module documentation to reflect the reality that Python is almost always (and as far as I can tell, that "almost" can be omitted) running on a machine whose C double supports signed zeros. Removes misleading references to functions being continuous from above / below / the left / the right at branch cuts Expands the note on branch cuts at the top of the module to explain the double-sided sign-of-zero-based behaviour Closes #85417 Issue: gh-85417
