Install ansible.posix.debug stdout callback plugin

ansible.builtin.debug is redirected to ansible.posix.debug.
We need to install the collection explicitly.

This needs to be fixed for stdout callback plugin related changes
in ansible-runner >=2.2.0.

Also, increases ansible verbosity to track these issues better in
the future.
