Add amethyst and cherry blossom slabs,stairs and walls

Minecraft has building variants for most materials, but amethyst and cherry blossom leaf blocks are missing some important options. I would love to see amethyst slabs, stairs, and walls added to the game. Amethyst is one of the most beautiful blocks in Minecraft, but you can't do much with it so builders cannot fully use it because it only exists as full blocks. These new variants would be perfect for magical builds, castles, temples, and decorative structures. I would also like cherry blossom leaf walls to be added. Cherry blossom is popular for Japanese-style builds, gardens, and villages, and walls would give builders more ways to create detailed designs. Adding these block variants would increase creativity, make existing materials more useful, and fit perfectly with Minecraft's current building system.
