fix(kuma-dp): advise user to check pod events when data plane rejected by webhooks

[jijiechen]

Checklist prior to review

• Link to relevant issue as well as docs and UI issues
  • Advise the user to check pod events when the data plane container will not become ready on Kubernetes #8256
• 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?
  • no need to update
• 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)
  • no need

@jijiechen can you rebase on release-2.5 so we include this in the up-coming release?

@jijiechen can you rebase on release-2.5 so we include this in the up-coming release?

Sure, I can do it. The two other two commits (by Bart and Krzysztof) will be removed from the PR, and they will stay on master, correct?
