Ensure that setuptools>=71 is not installed

gophish requires six==1.15.0, whereas setuptools>=71 requires
six==1.16.0.  The installation of setuptools>=71 ends up being a
problem when attempting to reinstall this package, since then
setuptools cannot be imported.  This is precisely what happens during
idempotence testing of cisagov/ansible-role-pca-gophish-composition,
so we must insist that only setuptools<71 is installed.
