Update PyPI publish CI

[pabloitu]

pypi gh-action should be updated to link the correct tag

From the CI;

You are using `pypa/gh-action-pypi-publish@master`. The `master` branch of this project has been sunset and will not receive any updates, not even security bug fixes. Please, make sure to use a supported version. If you want to pin to v1 major version, use `pypa/gh-action-pypi-publish@release/v1`. If you feel adventurous, you may opt to use use `pypa/gh-action-pypi-publish@unstable/v1` instead. A more general recommendation is to pin to exact tags or commit SHAs.

Please also consider migrating your setup to use secretless publishing: https://github.com/marketplace/actions/pypi-publish#trusted-publishing
