Minecraft Version: 1.21.5

NeoForge Version: 21.5.87

Description of issue:
I tried to override getAllEnchantments on an item to give a permanent enchantment effect, and it worked fine in 1.21.1, but after migrating to 1.21.5, it works only on a dedicated server and not on a local server. After investigating, it seems that the resolveLookup method in NeoForgeClientProxy returns null if the lookup is found. I believe the last "return null" should return lookup instead.
