Artifacts not uploaded to PyPI upon release

[eriknw]

I think this change made in #105 might not allow the upload to occur when doing a release:
84e41c2#diff-75627befeafda60a526c116b32f6fdef9bf57bcf456f840d7592c1d6f13facb4R196

I will upload the 8.2.0.1 artifacts to PyPI manually (once the download finishes 🤣)
