Docs: k8up removal

[SchoolGuy]

Summary

As "an administrator"
I want "to be able to easily remove k8up"
So that "I can reinstall it cleanly in case the operator messed up."

Context

During https://github.com/k8up-io/k8up/issues/834#issuecomment-1508012367 it became evident that some bugs are not triggered when deploying on a fresh cluster. As a clean re-deployment is IMHO not nice but an option I would like to know how to fully remove k8up so my FluxCD instance can reinstall it a few minutes later.
