kn service export doesn't work with traffic splits

[dprotaso]

Here's my sample knative service

apiVersion: serving.knative.dev/v1
kind: Service
metadata:
  annotations:
    serving.knative.dev/creator: kubernetes-admin
    serving.knative.dev/lastModifier: kubernetes-admin
  creationTimestamp: "2024-05-16T16:54:16Z"

  namespace: default

        client.knative.dev/user-image: ghcr.io/knative/helloworld-go:latest
      creationTimestamp: null
    spec:
      containerConcurrency: 0
      containers:
      - env:
        - name: TARGET
          value: Earth

        name: user-container
        ports:
        - containerPort: 8080
          protocol: TCP
        readinessProbe:
          successThreshold: 1
          tcpSocket:
            port: 0
        resources: {}
      enableServiceLinks: false
      timeoutSeconds: 300
  traffic:
  - latestRevision: true
    percent: 50
  - latestRevision: false
    percent: 50
    revisionName: hello-00001
status:
  address:
    url: http://hello.default.svc.cluster.local
  conditions:

    status: "True"
    type: RoutesReady
  latestCreatedRevisionName: hello-00002
  latestReadyRevisionName: hello-00002
  observedGeneration: 1
  traffic:
  - latestRevision: true
    percent: 50
    revisionName: hello-00002
  - latestRevision: false
    percent: 50
    revisionName: hello-00001
  url: http://hello.default.example.com

Exporting with revisions doesnn't include the second revisions

kn service export hello -o yaml --with-revisions
