Although this is a minor issue, it can lead to no recipe for the potentiometer if someone (like me) removes the copper wires of TFMG using KubeJS and uses copper wires of a new age instead.

Just change line 66 from Potentiometer recipe from "item": "tfmg:copper_wire" to "tag": "c:wires/copper"

potentiometer.json seems to be placed in the generated directory. Should this be changed in the datagen instead?
