    devel-docs, libgimpbase: getting rid of gimp_checks_get_shades().
    
    In the original gimp-2-10 branch where this feature was originally
    worked on, we had to keep gimp_checks_get_shades(). But on `master`
    where we will reset and break API, let's get rid of this function which
    should not be used anymore.
