    gtkshow: Document that gtk_show_uri is deprecated
    
    Due to the deprecation in gtkshow.h, there is proper deprecation warning
    for C code. But, for bindings (python in one case), there is no warning,
    due to missing "Deprecated:" annotation in gtkshow.c
    
    Fixes https://gitlab.gnome.org/GNOME/gtk/-/issues/3166
