Summary:

The default translation key for custom items is 'item.namespace:my_item' instead of 'item.namespace:my_item.name'.

Impact:

This issue breaks a lot of custom item names for those items not using the "minecraft:display_name" component, or those using it without setting a key. It forces the creator to use it to fix, or update their text files having an irregular item translate key that should be set by default as vanilla items are named.

Repro Steps:

1. Create a custom item in the new format.
2. Open it in game (enable EXPERIMENTAL: Holiday Creator Features).

Repro Rate: 3/3

Observed Results:
When this item is in use or hovered over, a key in format 'item.namespace:my_item' will be displayed as the item name.

Expected Results:

Default item translate key should be exactly like 'item.namespace:my_item.name', displaying it if no name is set in the text files or properly displaying the item name if set by text files.
