Bray & Cyber's Better, Fresher 3D Books

Updating Pack to function with all versions of Minecraft between 1.21.5-26.1.2.

Discontinuing official support for versions before 1.21.5. Mods have existed to allow this to happen in some capacity but development for those versions of Minecraft (when juggling using the mods and also the core shaders that allow for the emissive item effect to occur) has been more than I want to take on at this time.
