Bug description

when creating a kit with /createkit it doesnt save the item custom model data, i read on #2829 that it should.

Steps to reproduce

Give yourselft an item with a custom model data
use /createkit tools -1
use /kit tools

Expected behaviour

Items given have proper custom model data

Actual behaviour

items given dont have custom model data value

The issue you linked states that CustomModelData works if you add the NBT tag manually to the kit item inside the kits.yml file like below:

- itemname amount {NBT...}

If you want to use CustomModelData on kit items, you either need to manually add the NBT tag to the kit item itself, or if you're using a dev build, you can use the new use-nbt-serialization-in-createkit config option.
