bug: can not forward traffic to endpointslice

[cataglyphis]

Current Behavior

• k8s 1.33 do not support Endpoints, user EndpointSlice instead
• enable apisix ingress config watch_endpointslices: true
• add custom route as below

apiVersion: v1
kind: Service
metadata:
  name: automq
  namespace: automq
spec:
  type: ClusterIP
  clusterIP: None
  ports:
    - name: http
      port: 8080
---
apiVersion: discovery.k8s.io/v1
kind: EndpointSlice
metadata:
  name: automq
  labels:
    kubernetes.io/service-name: automq
addressType: IPv4
ports:
  - name: http
    port: 8080
endpoints:
  - addresses:
      - 10.180.4.62
    conditions:
      ready: true
---
apiVersion: apisix.apache.org/v2
kind: ApisixRoute
metadata:
  name: automq
  namespace: automq
spec:
  http:
    - name: automq-http
      match:
        hosts:
          - automq-nl.xxx.com
        paths:
          - /*
      websocket: false
      backends:
        - serviceName: automq
          servicePort: 8080
      timeout:
        connect: 10s
        send: 10s
        read: 10s

Expected Behavior

No response
