    extensions-app: Add category in .desktop file
    
    Predefined categories aren't a great way for organizing installed
    applications, but they have their use in "stores" like Software
    or flathub.
    
    Not listing any category means we fall through the cracks, so
    pick the (hopefully) least inappropriate one ...
