*: remove --insecure-allow-any-token option

~Since the authenticator is still used in e2e tests, don't remove
the actual package. Maybe a follow up?~

edit: e2e and integration tests have been switched over to the tokenfile
authenticator instead.

```release-note
The --insecure-allow-any-token flag has been removed from kube-apiserver. Users of the flag should use impersonation headers instead for debugging.
```

closes #49031
