I have Kubernetes version 1.31.5 with traefik v3.3.3. When I enable the experimentalchannel, the gateway api httproute will not work. Is this a known bug?

The issue is that the experimental feature must also be activated on the Kubernetes Cluster. Once I activate the feature, the traefik gateway api starts to work. I would be nice to have logs in traefik to highlight the missing feature from the kubernetes cluster.

`kubectl apply -f https://github.com/kubernetes-sigs/gateway-api/releases/download/v1.2.0/experimental-install.yaml`
