HWC Artifacts Fix

Originally created for use within my own modpack that I made for me and my friends.

In certain modpack setups, Artifacts' player.villager_reputation attribute fails to register on the Player entity, causing every villager trade attempt to crash. This mod fixes that by registering the missing attribute directly, no changes to Artifacts itself.

Requires NeoForge 1.21.1, and needs to be installed on both client and server.
