Tensura Reroller server-ready package

This package is based on Tensura Reroller 2.0.1 from CurseForge.
The reroll limits are configured in:
data/tensura_reroller/function/config.mcfunction

Server install:
1. Upload the datapack contents or the repacked zip to your server datapacks location.
2. Reload the server with /reload or restart it.
3. If needed, confirm the scoreboard setup by letting the datapack load once.

Current settings:
- RerollsAmount = 2
- RaceRerollsAmount = 1
- IsScrollResetable = 1
- ShowConfirmPrompt = 1

Behavior note:
- Existing players are automatically clamped to the configured skill and race reroll maximums.
- Players receive separate clickable chat entries for skill rerolls and race rerolls when available.
