docs: fix broken command examples in tasks

emmayusufu · emmayusufu · commit 864856025827 · 2026-06-09T06:47:42.000+03:00
Five small fixes where the example as written wouldn't run:
- network/extend-service-ip-ranges: heredoc needs `&lt;&lt;EOF`, not `&lt;EOF`
- manage-kubernetes-objects/storage-version-migration: the resource field takes
  the plural resource name `selfierequests`, not the kind `SelfieRequest`
- debug/debug-application/debug-service: EndpointSlice label is
  `kubernetes.io/service-name`, not `k8s.io/service-name`
- administer-cluster/kubeadm/adding-windows-nodes: code fence closed with six
  backticks instead of three
- administer-cluster/controller-manager-leader-migration: two kubectl patch
  commands had a stray trailing backtick
