Change: Use trusted publisher process to deploy on PyPI

[Trusted publisher](https://docs.pypi.org/trusted-publishers/) uses
OpenID Connect (OIDC) to issue short term tokens for GitHub. [Github
implements the OIDC standard](https://docs.github.com/en/actions/deployment/security-hardening-your-deployments/about-security-hardening-with-openid-connect)
since some month.
