[gnome-documents/wip/rishi/meson-submodule-update: 2/2] build: Ensure that the Git submodules are kept updated

    build: Ensure that the Git submodules are kept updated
    
    It's assumed that those building release tarballs, like distributions,
    might not have Git in their buildroots. Therefore, this is skipped for
    'plain' builds.
