  # `all_python_setup` amd `python_config` are a workaround for a known issue where it's not possible to use environment variables outside of `steps`.
  # Some jobs set up a text matrix which is outside of `steps` and environment variables can't be used directly. 
  # This requires a workaround based on the discussion in:
  # https://github.com/actions/runner/issues/2372
  # The limitation is captured here where certain job configurations don't have access to `env`
