[SPIKE] Pod Security admission has now entered beta

[eddie-knight]

"With the release of Kubernetes v1.23, Pod Security admission has now entered beta. Pod Security is a built-in admission controller that evaluates Pod specifications against a predefined set of Pod Security Standards and determines whether to admit or deny the pod from running. Pod Security is the successor to PodSecurityPolicy which was deprecated in the v1.21 release, and will be removed in Kubernetes v1.25." - are we ok from a Probr p.o.v.?
