Item Upgrader — v1.5.37 VV

- Corrected creator credits to YouTube: Cromos GG / CurseForge: CromosGG.
- Updated behavior and resource pack descriptions and author metadata.
- Refreshed the Help screen credit details and displayed version.
- Corrected translated creator credits while preserving translation keys.
- Replaced outdated installation instructions with current update guidance.
- Retained Mojang asset attribution and license files.
- Preserved item values, probabilities, recipes, gameplay rules, UI layouts,
