PR Summary

• Improvement of the User Manual (README.md)
  Updated the manual to provide information about a new fix related to the Black Hole Tank that prevents the loss of buckets if the player's inventory is already full.

• Added Configuration Option (UTConfigMods.java)
  Introduced a new setting utFixBlackHoleTankVoiding that allows users to control whether they want to use the updated functionality of the Black Hole Tank or not.

• Enhanced Functionality (UTMixinLoader.java)
  Adapted the functionality to apply the Black Hole Tank fix only when the user has enabled it through the setting utFixBlackHoleTankVoiding.

  Created new JSON file to record these changes in the Black Hole Tank rules, ensuring the consistency and stability of the new features.
