fix: revert to vanilla brewing stand remainder mechanic

[jebibot]

Fabric API (https://github.com/FabricMC/fabric/blob/1.20.4/fabric-item-api-v1/src/main/java/net/fabricmc/fabric/mixin/item/BrewingStandBlockEntityMixin.java) modifies the last remainder mechanic, so there is no need to fix it on the Arclight side and it actually causes a mixin conflict:

java.lang.NullPointerException: Cannot invoke "net.minecraft.class_1799.method_7960()" because the return value of "java.lang.ThreadLocal.get()" is null
