Hide invited group name and source from project/group non-admins

What does this MR do and why?

If a group invited to a project/group is not visible to the current user we mask the source. The visibility was determined by:

1. The current user can read the invited group.
2. The current user is a member of the shared group.

We're changing point 2 above to:

The current user is the admin of the shared group/project i.e. having at least maintainer access in the shared project or having owner access in the shared group.

!146995 (merged) will update the relevant documentation.
