Operators: Turn examples into documentation

We have the example directories in the operators, which are very useful for us devs to quicky deploy an instance of something. But the examples are not tested.

With the getting started guide we started moving examples into the docs and testing them. It would make sense to keep doing this, with the other examples as well. There are specific examples which deploy an instance + OPA etc., which we could turn into specific docs guides.

This would be an epic and needs to be done for all operators.

Start by reviewing the operator example directories and the getting started guide, where examples have begun moving into tested documentation. Inventory the remaining examples across all operators, identify which should become specific guides, and define completion as each selected example being documented and tested.
