Upgrade Python version to 3.12 across all CI/CD workflows and package requirements

- Update all GitHub Actions workflows to use Python 3.12 (from 3.11, 3.9.x, 3.9, and 3.x)
- Update pyproject.toml minimum Python version requirement from >=3.9 to >=3.12
- Update Python version check in test-json-schema-to-grammar.cpp from 3.8 to 3.12
- All tests passing (37/37) and build successful after upgrade
