docs: <p>
  Updates an Amazon EKS cluster to the specified Kubernetes version. Your cluster continues to function during the
  update. The response output includes an update ID that you can use to track the status of your cluster update
  with the <a>DescribeUpdate</a> API operation.
  </p>
  <p>
  Cluster updates are asynchronous, and they should finish within a few minutes. During an update, the cluster
  status moves to <code>UPDATING</code> (this status transition is eventually consistent). When the update is
  complete (either <code>Failed</code> or <code>Successful</code>), the cluster status moves to <code>Active</code>
  .
