Use the stackit_ske_kubeconfig resource instead. For more information, see How to rotate SKE credentials (https://docs.stackit.cloud/stackit/en/how-to-rotate-ske-credentials-200016334.html).

To get the current kubernetes version being used for your cluster, use the `kubernetes_version_used` field.
