Setuptools v54.1.0 introduces a warning that the use of
dash-separated options in 'setup.cfg' will not be supported
in a future version [1].
Get ahead of the issue by replacing the dashes with underscores.
Without this, we see 'UserWarning' messages
like the following on new enough

  UserWarning: Usage of dash-separated 'description-file' will not be
      supported in future versions. Please use the underscore name
            'description_file' instead
