Names of Mobs and items added from Mounts of Mayhem are no longer translated in release 26.0

Steps to reproduce:

1. Make sure the game language is set to ones other than English

2. With Minecraft open, click Play

3. Enter a world (with cheats enabled)

4. Send “/give @s wooden_spear" (give yourself a spear) (or others added from Mounts of Mayhem, i.e. Nautilus spawn egg, Copper spear, etc), or grab some from the Creative inventory

5. Observe the name of an item

Expected result: The names should be translated

Observed result: Wooden Spear and more, but not including Zombie Horse, are no longer translated.

Note: Based of https://github.com/Mojang/bedrock-samples/tree/main/resource_pack/texts , it affects every language other than English.
