Do PyPI release in GitHub Actions (#155)

This workflow is based on https://learn.scientific-python.org/development/guides/gha-pure/

This introduces GitHub Actions (GHA), alongside CircleCI. An additional integration is not ideal, but this gets us some community-supported tooling and more secure handshaking between GitHub and PyPI for publishing via "Trusted Publisher" so we don't need to manage secrets: https://docs.pypi.org/trusted-publishers/
