Add AuthorizedToSee trait to MenuGroup

[jeremythiou]

Nova version: 4.11.1

Hi!
In the release note for the v4.2.5, I can see the AuthorizedToSee trait has been added to the MenuSection, MenuItem and MenuGroup classes but the MenuGroup class does not have that trait.

Is it possible to add this trait to the MenuGroup class so it is possible to hide a Group and its Items in cascade?

The behavior would be like the current MenuSection: if I don't authorize to see a section, all the children (groups and items) are hidden.

In my case all my items are hidden because of policies and the group is still displayed but empty. An alternative would be to add a feature to hide the group automatically if it is empty?
