0635422c - rename STUBS_NOT_INSTALLED to APPROVED_STUBS_NOT_INSTALLED (#10558)

rename STUBS_NOT_INSTALLED to APPROVED_STUBS_NOT_INSTALLED (#10558) Since this code path involves mypy recommending installation of a stub package, I thought I'd rename the enum to make it slightly clearer that this should only be triggered for packages we know to be good.
