kiali: Kiali-operator installed view-only kiali has permissions issue on namespaces causing the graph to break

Describe the bug Kiali goes back and forth between showing the graph and breaking over a permissions issue: A clear and concise description of what the bug is. namespaces is forbidden: User "system:serviceaccount:istio-system:kiali-service-account" cannot list resource "namespaces" in API group "" at the cluster scope

Versions used Kiali: 1.25.0 Istio: 1.7.3 Kubernetes flavour and version: AKS 1.18.8

To Reproduce

1. install Kiali-operator using the helm chart

values:
  clusterRoleCreator: true
  cr:
    namespace: istio-system
    name: kiali
    create: true
    spec:
      istio_namespace: istio-system
      auth:
        strategy: "anonymous"
      deployment:
        view_only_mode: "true"
        accessible_namespaces:
          - '**'
        image_name: "quay.io/kiali/kiali"
        image_pull_policy: "IfNotPresent"
        image_version: "v1.25.0"
        ingress_enabled: false
        namespace: "istio-system"

1. go to Kiali UI and click on graph, wait a little while. Graph will switch between showing and breaking, posting messages to message center.

Expected behavior In docs it says that a view-only kiali should get a kiali-viewer clusterrole but that isn’t created in my cluster. Whenever I do a kubectl auth can-i list namespaces --as system:serviceaccount:istio-system:kiali-service-account --all-namespaces it returns yes so I expect it to work. However, the graph breaks and I get those error messages in message center.
