Revert "Add ensure-reno and ensure-babel roles"

This breaks building of releasenotes since we now have
both a version of this role in openstack-zuul-jobs and zuul-jobs. The other files expect that .venv/bin is used
but this change installs in user.

Revert for now - we can revert this again later once the full
stack is tested.

This reverts commit fa63c7b555017f8e9d41a1e8c18ece943f0eb0b1.
