Failing Microsoft extensions due to min Python version

ms-python.autopep8, ms-python.black-formatter, ms-python.flake8, ms-python.mypy-type-checker, ms-python.pylint all require Python 3.9 now: https://github.com/microsoft/vscode-flake8/commit/68a8a6c02f4dc7006384cfe94197db485a200aeb I think they're failing to publish because the publish job is using Python 3.8.

Start by tracing the publish job configuration and identifying which Python runtime it uses. Compare that runtime with the Python 3.9 requirement in the linked vscode-flake8 commit and check the publishing path for the listed Microsoft extensions. Done means those extensions publish successfully with the required Python version.
