[recipes] Add a quick help menu item

[Matthias Clasen <matthiasc src gnome org>]

commit c73c3764c6bd958496dcd11c3ca1a52d99d0539c
Author: Matthias Clasen <mclasen redhat com>

    Add a quick help menu item
    
    This uses g_app_info_launch_uris, which turns out
    to work ok inside a sandbox that has yelp in it.
    We avoid the launch-default API, since that will
    always go via the portal, and we need to avoid
    the portal here.
