Kubernetes API 1.25 migration

This article applies Kubernetes 1.25 migration to the hivemq-operator helm chart.

According to the Kubernetes 1.25 migration , PodSecurityPolicy in the policy/v1beta1 API version will no longer be served in v1.25, and the PodSecurityPolicy admission controller will be removed. Kubernetes recommends to Migrate to Pod Security Admission or a 3rd party admission webhook.

At the moment we don't have an alternative to enforce security policies, so this should be considered a workaround. The workaround is to disable the PodSecurityPolicy. How to do it is explained in the instructions below.
