Further improve mypy_test.py (#7484)

Browse Source 
* Run mypy on the 3.11 stdlib in CI, as a regression test for https://github.com/python/mypy/issues/12220
* Correct the docstring at the top of the file following the changes made in #7478
* Stop the test from crashing when run locally if there's an extra file/folder in the stubs directory.
