Bugfix: Missed ClusterRole for secrets-store-csi-driver-provider-gcp-role

When configuring the Secrets Store CSI driver I missed the ClusterRole definition. Add it:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: secrets-store-csi-driver-provider-gcp-role
rules:
- apiGroups:
  - ""
  resources:
  - serviceaccounts/token
  verbs:
  - create
- apiGroups:
  - ""
  resources:
  - serviceaccounts
  verbs:
  - get
