[gimp] plug-ins: use gimp_procedure_dialog_set_sensitive().

[Jehan <jehanp src gnome org>]

commit 2f46dfb354e3498d2fd02e80279a3943d44fbdbc

    plug-ins: use gimp_procedure_dialog_set_sensitive().
    
    In PNG, JPEG and TIFF export plug-ins which use the new API, use our new
    function to set widget sensitivity.
    
    Note that part of it is similar to commit 6a2910bd3b on `gimp-2-10`,
    making "Save GeoTIFF data" checkbox insensitive when there are no such
    data available (this feature was late on the main branch as we rushed
    for 2.10.24 release).
