Remove deprecated traceback formatting argument. (pantsbuild#15320)

The [`etype` argument to `format_exception`](https://docs.python.org/3/library/traceback.html#traceback.format_exception) has been ignored since Python `3.5`, and is removed in Python `3.10`. Fixes pantsbuild#15310. [ci skip-build-wheels]
