Subject: [PATCH] cmd/k8s-operator: add priorityClassName support to helm chart
 (#19236)

Expose priorityClassName in the operator Helm chart values so that
users can configure the operator deployment with a Kubernetes
PriorityClass. This prevents the operator pods from being preempted
by lower-priority workloads.

Fixes #19235
