Logging test fails for new astropy file overwrite error message

Astropy PR #12179 changed the error message when trying to overwrite an existing file without specifying overwrite=True. Our logging tests fail to catch this new error message when testing with the astropy main branch. See recent compatibility workflow logs or reproduce locally on the skypy main branch:
