feat(frontend): add componentversions RBAC permissions to cluster-version-reader

[Copilot]

The cluster-version-reader ClusterRole lacks permissions for componentversions resources in the apps.kubeblocks.io apiGroup, preventing the dbprovider frontend from querying component version information.

Changes

Added RBAC rule to frontend/providers/dbprovider/deploy/manifests/rbac.yaml:

- apiGroups: ['apps.kubeblocks.io']
  resources: ['componentversions']
  verbs: ['get', 'watch', 'list']

This grants the cluster-version-reader service account read-only access to componentversions, consistent with existing permissions for clusterversions and other KubeBlocks resources.
