The version specification of pyarrow seems not to fulfill [PEP 440 (Version Identification and Dependency Specification)](https://peps.python.org/pep-0440/). I think it's a typo. https://github.com/googleapis/python-bigquery/blob/929276949244f704688837dfca35cb7dacd44623/setup.py#L54 Due to this designation, some tools (e.g. [Poetry](https://python-poetry.org/)) detect it and fail when installing and/or locking packages.
