    actions-popover: Save screenshots into ~/Pictures/Screenshots
    
    Ever since GNOME Shell 42, the screenshots are now saved under
    XDG_PICTURES_DIR/Screenshots.
    
    Boxes will attempt to create the directory if it doesn't exist.
    
    This directory name is translatable and both GNOME Boxes and GNOME
    Shell translations for the directory name should be the same for
    the same folder to be used.
    
    Fixes #776
