Fix tribe node cluster state version increments (#25629) 

With #24236, tribe nodes submit cluster state changes to their MasterService, making it unnecessary to explicitly update the cluster state version. This PR fixes the double-incrementing of cluster state versions on tribe nodes, which are not harmful, but unnecessary.
