do not delete chaos-mesh namespace

[csuzhangxc]

chaos testing hasn't been working for a long time, so we disable this Action now and may enable it again (and make it work) later.

• the chaos YAML has pingcap namespace, but this namespace will be cleaned in

  Lines 87 to 115 in 27e71c7

  	if framework.TestContext.CleanStart {
  	reservedNamespaces := []string{
  	metav1.NamespaceSystem,
  	metav1.NamespaceDefault,
  	metav1.NamespacePublic,
  	v1.NamespaceNodeLease,
  	}
  	if framework.TestContext.Provider == "kind" {
  	// kind local path provisioner namespace since 0.7.0
  	// https://github.com/kubernetes-sigs/kind/blob/v0.7.0/pkg/build/node/storage.go#L35
  	reservedNamespaces = append(reservedNamespaces, "local-path-storage")
  	} else if framework.TestContext.Provider == "openshift" {
  	reservedNamespaces = append(reservedNamespaces, "openshift")
  	}
  	deleted, err := framework.DeleteNamespaces(c, nil, reservedNamespaces)
  	if err != nil {
  	log.Failf("Error deleting orphaned namespaces: %v", err)
  	}
  	// try to clean up backups
  	if err := ForceCleanBackups(c, extClient, apiExtClient); err != nil {
  	log.Failf("Error clean backups: %v", err)
  	}
  	log.Logf("Waiting for deletion of the following namespaces: %v", deleted)
  	if err := framework.WaitForNamespacesDeleted(c, deleted, framework.DefaultNamespaceDeletionTimeout); err != nil {
  	log.Failf("Failed to delete orphaned namespaces %v: %v", deleted, err)
  	}
  	}

• the ginkgo focus for chaos mesh is Restarter (https://github.com/pingcap/tidb-operator/blob/27e71c73f50152da6222322650c4f6de405d1165/.github/workflows/chaos.yaml#L60C52-L60C61), but this case has been removed in Remove the PodRestarter controller and tidb.pingcap.com/pod-defer-deleting annotation #3296
