Create the 'About discussion' widget

There should be an aboutdiscussion widget that has 2 different tabs. The first tab is the Details tab and shows the metadata of the discussion (title, description, created by). When a description is not available, it should not be shown. The second tab is the Shared with tab and shows the list of members of the discussion.
This check can just be `{if groupProfile.createdBy.profilePath}`
