message: Fix app repository role
  The button `Refresh` of the app repositories view didn't work because of this error:
  ```
  'events "artifactory.153c4d4c29911fd9" is forbidden: User "system:serviceaccount:kubeapps:apprepository-controller" cannot patch events in the namespace "kubeapps": Unknown user "system:serviceaccount:kubeapps:apprepository-controller"'
  ```
  Adding the required permission.
