[gnome-shell/4948-replicate-gs-folders-c-from-the-gnome-software] main: Initialize app folders for the Applications grid on start

[Milan Crha <mcrha src gnome org>]

commit 6b93787f9490619b29263b8cc752e4b8d9031863

    main: Initialize app folders for the Applications grid on start
    
    Set the default folders and applications for the Applications grid on start.
    The code used to be in gnome-software, but since the gnome-software does not
    edit the settings on its own anymore, the split between setting the defaults
    and using the settings keys only caused confusion.
    
    Closes https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4948
