Description
In #10721, the seaborn stubs depend on matplotlib that only included a py.typed marker file in version 3.8.
matplotlib version 3.8 requires python >=3.9 which leads to the mypy tests failing on python 3.8.
Alex Waygood suggests adding a requires-python field to METADATA.toml and teaching stub-uploader to include it in the generated setup.py https://github.com/python/typeshed/pull/10721#issuecomment-1722454399.

Research direction
Start by reviewing METADATA.toml, stub-uploader, and the generated setup.py path described in the issue, then reproduce the mypy test failure on Python 3.8 caused by the seaborn and matplotlib dependency. Compare the proposed requires-python metadata flow with the existing package generation behavior. Done means the supported Python requirement is represented in generated packages and the Python 3.8 tests no longer fail for this case.
