Looking at the different PXC operator installation methods, particularly checking my notes from 1.6.0, we replaced a series of deploy/<file>.yaml with a single bundle.yaml, e.g.:
https://www.percona.com/doc/kubernetes-operator-for-pxc/eks.html
https://www.percona.com/doc/kubernetes-operator-for-pxc/gke.html

whereas the "generic" installation doc remains using the old procedure:
https://www.percona.com/doc/kubernetes-operator-for-pxc/kubernetes.html

The operator approach is not a straightforward one, it would be nice to depict what bundle.yaml does on the docs in view of the steps bundled together in that file, even because one might still want to run each of them separately; I've just tested doing so, it still works.
