Steps to reproduce

1. Create a new world with Villager Trade Rebalance enabled in experiments

2. Create a Librarian villager setup and summon only one villager to acquire Librarian

3. trade anywhere to gain master level to see this menu of name tag

Expected behavior: Master level Librarian villagers shouldn’t sell name tags when Villager Trade Rebalance is enabled in some worlds
