CI: Switch to pytest-ansible

The functionality provided by pytest-molecule been merged into the
pytest-ansible plugin. The repository has been archived [1].

Switch to pytest-ansible for the molecule job. We need to disable
pytest-ansible when running testinfra because they define the same
--ansible-inventory option [2].

Make the kayobe-tox-molecule job voting again.
