Suspicious Zombification

- Renamed Zombie's Curse/Grace to Zombies' Curse/Grace (singular to plural)
- Fixed crashes that could happen in conjunction with other mods during animal conversion
- Added new configuration settings for more control over some of the mod's features:
  - Disable zombified animals being able to zombify their prey on Normal and Hard difficulty
  - Disable zombified cats giving morning gifts
  - Disable players with the Zombies' Curse effect zombifying animals in their range
- Added support for chicken, cow, and pig variants
  - Zombified animal textures are now overlays instead of full edits of the base texture
  - This means custom animal variants added by datapacks are supported as well
  - Variants are kept the same between zombification and curing
- Added blue and brown rotten egg
  - Can be used where the normal rotten egg can be used and work the same
  - Eggs are dropped by the corresponding zombified chicken variant
  - Zombified chickens have a custom egg laying loot table: `#suszombification:gameplay/zombified_chicken_lay`
