[IMP] Discuss: Canned responses update

Previously, the documentation described canned responses with a description field,
no explicit shortcut indicator, and included default filters in the view.

Now, the description field has been removed, and the UI displays `::` as the shortcut prefix,
and default filters have been removed from the view.
