Add missing RBAC permissions for metal3clustertemplates

Fixes RBAC permission error where capm3-manager service
account could not list metal3clustertemplates resources.

Error fixed:
metal3clustertemplates.infrastructure.cluster.x-k8s.io is
forbidden: User "system:serviceaccount:capm3-system:capm3-manager"
cannot list resource "metal3clustertemplates"
