problems with lights below 0, raw mineral textures not updated and deepslate generation problems

in version 1.17.0.52 I found several errors in the area generated below zero: the shadows of the blocks is absent (with active settings). another problem is in the generation of the "Deepslate: under the 0 coordinates it is absent. the textures of the minerals and rough blocks have not been updated to the latest java version. I hope my contribution is useful and I wish you good work
