fix: use PySide6 for Maya 2025 (Python 3.11+) compatibility

- Add Python version detection in Maya test script
- Use PySide6>=6.2.0 for Python 3.11+ (Maya 2025)
- Keep PySide2>=5.15.2.1 for Python 3.10 and below (Maya 2022-2024)
- Resolve PySide2 version compatibility issue with Python 3.11

Maya 2025 uses Python 3.11.4, but PySide2 5.15.2.1 only supports up to
Python 3.10. This change ensures the correct Qt binding is installed
based on the Python version in each Maya Docker container.
