AntiShulkerDupe - Fix for Shulker Duplication Bug

This mod addresses a critical bug discovered in Minecraft versions 1.17 through 1.19 that allowed unlimited duplication of items from shulkers. After installing this fix, exploitation of this bug becomes impossible.

It's important to note that starting from version 1.19.1, Mojang developers independently resolved this issue at the game level, so in newer Minecraft versions, using this mod is not necessary.
