2.5.0 for Fabric 1.21.8

Changed how whetstone durability works:
- Durability reduced from 12 to 6.
- Now has a chance to get damaged on use instead of always taking damage.
- Is twice as likely to get damaged on use compared to the anvil.
- Item name and texture change based on damage (Whetstone -> Chipped Whetstone -> Damaged Whetstone -> Broken Whetstone).
Anvils now turn into a Broken Anvil when used up instead of being destroyed.
- Right-clicking a broken anvil does not open the anvil screen.
- If the anvil breaks while you're in the anvil screen, you won't be able to do any operations.
- Right-clicking an anvil with an iron block repairs it by one stage.
