docs(MADR): add Kubernetes UX for MeshService

[michaelbeaumont]

Checklist prior to review

• Link to relevant issue as well as docs and UI issues -- MADR for Kubernetes UX of MeshService  #9704
• This will not break child repos: it doesn't hardcode values (.e.g "kumahq" as a image registry) and it will work on Windows, system specific functions like syscall.Mkfifo have equivalent implementation on the other OS --
• Tests (Unit test, E2E tests, manual test on universal and k8s) --
  • Don't forget ci/ labels to run additional/fewer tests
• Do you need to update UPGRADE.md? --
• Does it need to be backported according to the backporting policy? (this GH action will add "backport" label based on these file globs, if you want to prevent it from adding the "backport" label use no-backport-autolabel label) --

Not really too much to add, would be good to see an example as mentioned by Marcin.

It's really hard to do another review when it's force pushed. I see you added the example (the thing that I mentioned in the previous review).

I'm still not very convinced by the headless service implem...

The rest looks great though!
