Remove RBACs for persistentvolumes (#1203)

## Summary

Remove `persistentvolumes` RBAC permissions from the HCCM ClusterRole
and update the generated Helm snapshots/manifests accordingly.

## Why

HCCM does not use `PersistentVolume` objects directly.

The only references in this repository were RBAC entries in:
- the Helm ClusterRole template
- the rendered deployment manifests
- the Helm snapshot fixtures

A code search found no `PersistentVolume` handling in the Hetzner CCM
implementation itself. The permission appears to have been carried over
from broader upstream CCM RBAC guidance, but it does not appear to be
required for this provider.
