What does this PR do?

This change addresses the Kubernetes 1.25 compatibility issue caused by Operator attempting to handle PodDisruptionPolicy resource not available in aforementioned version.

Operator 1.0.0 deployed on v1.25 would log following error on every reconcile

{"level":"ERROR","ts":"2023-01-17T21:19:23Z","logger":"controller.datadogagent","msg":"Reconciler error","reconciler group":"datadoghq.com","reconciler kind":"DatadogAgent","name":"datadog","namespace":"system","error":"no matches for kind \"PodSecurityPolicy\" in version \"policy/v1beta1\"","errorCauses":[{"error":"no matches for kind \"PodSecurityPolicy\" in version \"policy/v1beta1\""}]}

Motivation

Make Operator 1.0.0 run on v1.25.

Additional Notes

This change does not solve PSP usage across Operator.

PSP resource isn't utilized/implemented (see this) and only places attempting to handle PSP were resource cleanup routines. This PR changes the logic producing list of Kinds for the cleanup - it includes PSP only if it's supported by current Kubernetes version.

Once PSP resource implementation is done additional work will be need to control PSP creation.

Describe your test plan

Tested Kubernetes version 1.24, 1.25 using Kind cluster. Deployed agent locally, installed DDA v2 with DCA, CCR enabled - confirmed no errors are thrown.
