missing doc to create a secret for gateway api HTTPS protocol

[Jooho]

Expected Behavior

Doc should explain how to create the TLS secret for gateway API HTTPS protocol

it should be working with this doc

kubectl get svc kserve-ingress-gateway -l serving.kserve.io/gateway=kserve-ingress-gateway -A

but it showed nothing because the gateway is not adding the label properly because the secret does not exist

    - attachedRoutes: 2
      conditions:
      - lastTransitionTime: "2025-03-17T20:34:30Z"
        message: Secret kserve/my-secret does not exist.
        observedGeneration: 1
        reason: InvalidCertificateRef
        status: "False"
        type: ResolvedRefs
      - lastTransitionTime: "2025-03-17T20:34:30Z"

        kind: HTTPRoute
      - group: gateway.networking.k8s.io
