Kuma tags wrong service of delegated gateway

[lukidzi]

Kuma Version

master

Describe the bug

When we deploy the delegated gateway, Kuma attempts to tag the service of the delegated gateway. Unfortunately, the delegated gateway has three services, and the tagged service is a metrics service. This causes policies to be incorrectly matched.

With MeshService it shows gateway unavailable

#12746

To Reproduce

Follow the guide https://kuma.io/docs/2.9.x/guides/gateway-delegated/

Expected behavior

We should do the best effort to tag the right service

Additional context (optional)

Triage: lets check if there is kuma.io/gateway annotation on the controller and that should be the case.
