[Milan Crha <mcrha src gnome org>]

commit 6f5e3f79ae8fda4508261a00a6663b1bd9429dd6

    webapps: Search for apps by app id
    
    The `keywords` list is used to search for an (installed) app, to show
    its details, like from the Activities and the app context menu in the Shell.
    No other plugin knows about installed web apps, thus search for them by
    the app id.
    
    Closes https://gitlab.gnome.org/GNOME/gnome-software/-/issues/1927
