Update PyPA "publish to PyPi" github action (#1073)

Summary:
Pull Request resolved: #1073

Uh oh! On our actions page it tells us we are using an old version of the PyPA "publish to PyPi" github action. It looks like they sunset the "master" brand (ie no more updates, not even security) and want us to use this new one instead. Screenshot attached.
