[Milan Crha <mcrha src gnome org>]

commit 5263d7b18e9fc801fd7380a382eea3da36992b0a

    gs-plugin-appstream: Invalidate the silo after install/update/remove is finished
    
    These actions can cause changes on the disk, which are not always
    noticed by the XbSilo, thus explicitly request a refresh of the XbSilo
    to ensure an up-to-date state is used by this plugin.
    
    Closes https://gitlab.gnome.org/GNOME/gnome-software/-/issues/1422
