Subject: [PATCH] PY-57541 PY-53896 Add missing AnyStr_co to partially updated
 Typeshed

Its absence made Py3TypeCheckerInspectionTest.testPathlibPathMatchingOsPathLike
fail as os.PathLike protocol wasn't considered generic. Once the changes
for generics are in the upstream, we will be able to update the Typeshed
fully at long last.
