ansible-lint: Adjust pre-commit hooks dependencies

Dropping the ansible dependencies for ansible-lint will allow us to
catch missing dependencies collections in galaxy.yml. For collections
needed for contrib/ or tests/ (i.e: not part of core kubespray
dependencies), we can just configure ansible-lint to mock them.

This mean it won't check the mocked module parameters, but for those
area of the code base it's an acceptable trade-off.
