Also update the pypi publish action to avoid this email from PyPi:

[PyPI] Deprecation notice for recent source distribution upload to 'NREL-reVX

This email is notifying you of an upcoming deprecation that we have determined may affect you as a result of your recent upload to 'NREL-reVX'. 
In the future, PyPI will require all newly uploaded source distribution filenames to comply with PEP 625. Any source distributions already uploaded will remain in place as-is and do not need to be updated. 
Specifically, your recent upload of 'NREL-reVX-0.3.61.tar.gz' is incompatible with PEP 625 because the filename does not contain the normalized project name 'nrel_revx'. 
In most cases, this can be resolved by upgrading the version of your build tooling to a later version that supports PEP 625 and produces compliant filenames. You do not need to remove the file.
