fix(ci): pin setuptools<81 so pylama can import pkg_resources

setuptools 81 removed pkg_resources; latest (83) breaks pylama 8.4.1's
'from pkg_resources import iter_entry_points'. Pin <81 at install time and
re-assert right before lint (the access_modules --ignore-installed step can
pull a newer setuptools).
