Sort "custom_model_data" when merging resource packages.

[XXY233]

"custom_model_data" should be sorted from smallest to largest when merging resource packs, otherwise minecraft will not handle the "custom_model_data" correctly, resulting in unexpected behavior.

Because I encountered strange behavior in the 1.20.4 client, the item NBT "custom_model_data" was 2200001. But it used the model "magic:wands/enchantedbook" instead of "slimefun:slimefun/gui/slimefun_guide".

(I used machine translation, so I'm sorry if there's any confusion.)
