[gnome-builder] dep-updater: add new interface for updating dependencies

[Christian Hergert <chergert src gnome org>]

commit e22aa0a4378fb58569589ebeceaeb4e22833b78a
Author: Christian Hergert <chergert redhat com>

    dep-updater: add new interface for updating dependencies
    
    This gives us an interface that plugins can implement to update
    dependencies. The omnibar will activate this command instead of
    the flatpak-specific backend.
    
    This should allow plugins for other languages such as NodeJS or
    Pip to provide an updater in a similar fashion.
