terraform apply always update the cluster

[angeloudy]

Since I upgraded the rke provider to 0.13.
Every time I ran terraform apply, it always tries to update the cluster even though nothing changes.

id                        = "89a1fd84-8c85-475f-b8c8-026cb7f5b3c8"
        ignore_docker_version     = false
        inactive_hosts            = []
        internal_kube_config_yaml = (sensitive value)
        kube_admin_user           = "kube-admin"
      ~ kube_config_yaml          = (sensitive value)
        kubernetes_version        = "v1.21.7-rancher1-1"
      ~ rke_cluster_yaml          = (sensitive value)
      ~ rke_state                 = (sensitive value)
