`setup.cfg` contains a setting to create a `Universal Wheel` which is only needed if libraries support both Python 2 and Python 3. This library only supports Python 3 so this setting is no longer needed. See https://packaging.python.org/en/latest/guides/distributing-packages-using-setuptools/#wheels.

See similar PR https://togithub.com/googleapis/google-cloud-python/pull/13659 which includes this stack trace

              With Python 2.7 end-of-life, support for building universal wheels
              (i.e., wheels that support both Python 2 and Python 3)
              is being obviated.
              Please discontinue using this option, or if you still need it,
              file an issue with pypa/setuptools describing your use case.
      
              By 2025-Aug-30, you need to update your project and remove deprecated calls
              or your builds will no longer be supported.

* feat: Add Python 3.13 updates for repo settings and Kokoro

Includes additional updates for Python 3.13 support:

- Adds 'unit (3.13)' to the required status checks in the repo settings file (`.github/sync-repo-settings.yaml`).
- Populates and updates Kokoro sample configuration files in `.kokoro/samples/python3.13/` to mirror the 3.12 setup, adjusting version-specific variables.

* feat: Drop support for Python 3.7 and 3.8

Removes support for Python 3.7 and 3.8, establishing Python 3.9 as the new minimum supported version.

This change involves:
- Updating `python_requires` and classifiers in `setup.py`.
- Modifying Python versions in `noxfile.py` (default, unit tests, system tests) and ensuring constraint file logic remains correct.
- Updating the GitHub Actions workflow (`unittest.yml`) matrix, runner, and coverage job version.
- Deleting constraint files for Python 3.7 and 3.8 (`testing/constraints-3.7.txt`, `testing/constraints-3.8.txt`).
- Removing Kokoro sample configuration directories (`.kokoro/samples/python3.7/`, `.kokoro/samples/python3.8/`).
- Updating supported version mentions in `README.rst`.
- Removing 3.7 and 3.8 from the `ALL_VERSIONS` list in `samples/snippets/noxfile.py`.
