Ticket of eternal keep

### 🎉 New Features

- **Configurable Loot Table Probabilities**: You can now fully customize the ticket spawn probabilities for each structure through the `ToEK.json` configuration file
  - Individual configuration for each specific loot table
  - Configurable generic probability for other chests
  - Default values maintained for backward compatibility

- **Nether Fortress Support**: Added support for tickets to spawn in Nether Fortress chests with a default probability of 5%

- **Extended Compatibility**: The mod is now compatible with Minecraft versions from 1.21 to 1.21.3 with a single JAR
