Crash when the sum of enchantments' weights overflow

Summary
When an enchantment has a big weight (close to Integer.MAX_VALUE), adding other enchantments' weights will make the total exceed the integer limit, causing a crash.

Steps to Reproduce

1. Create a world with the attached data pack, which makes the Sharpness enchantment have Integer.MAX_VALUE weight.

2. Summon a villager.

3. Place a grindstone.

Expected Result
The data pack should fail to load, or no crash should occur.

Actual Result
Game crashes.
