    meson.build: Depend on webkit2gtk-4.1 if available
    
    Build against webkit2gtk-4.1 if available, falling back to webkit2gtk-4.0.
    
    webkit2gtk-4.1 has the same API as webkit2gtk-4.0, so no code changes
    are needed, but it links against libsoup-3.0 instead of libsoup-2.4.
    
    See https://discourse.gnome.org/t/removing-libsoup-2-for-gnome-45/10846
    for some discussion.
