helm: Fix PDB apiVersion to allow K8s 1.25+ deployment

[jwitko]

Description

The Apache Druid helm chart can not currently be deployed on Kubernetes v1.25+ with PodDisruptionBudgets enabled. The API Version being used (policy/v1beta1) has been removed in Kubernetes 1.25. This PR allows for the updated policy version when helm can determine that the cluster version is >1.21 (when the API was deprecated). It also paves the way for a place and style to do other changes of this nature.
