awx example requires deprecated role geerlingguy.awx

[dirks]

The role geerlingguy.awx required in awx/requirements.yml is deprecated. Since the installation of awx has been changed to a kubernetes operator and the last few awx issues have been closed by the stale bot, I suggest to remove this example from the repo.

Definitely; that example was the most fragile anyways. Would be good to pop it out.
