Compatibility with Python 3.8 and 3.9 has been removed

### Changed
- Removed support for Python 3.8 and 3.9 from `pyproject.toml` and updated the `requires-python` field to require Python 3.10 or higher.
- Adjusted the `target-version` in the Black configuration to reflect the removal of older Python versions.
- Updated the CI workflow to only include Python versions 3.10 and above in the matrix.
