Steps to reproduce

• In the config YAML, add a `label` property to an app group. ie

  groups: 
    - name: content
      label: MY CONTENT GROUP
      apps: 
        - pages-app
        - dam
        #etc.
  

• Open admin central

Expected results

• As apps, dialogs, fields, actions, etc. can all be labelled directly in YAML using the `label` property, it might be reasonable to expect the group label to show "MY CONTENT GROUP".

Actual results

• The property has no effect (as confirmed by Definitions app) and the group is labelled "app-launcher.content.label".

Workaround

• App groups can only be labelled via a message bundle.
