OIDC-based releases

[JBWilkie]

Problem

Currently, we use static user credentials for PyPi to release new darwin-py versions. Ideally, static credentials should not be used

Solution

This PR adjusts the release process to authenticate with PyPi via OIDC, which uses short-lived tokens. This guide was followed: https://docs.github.com/en/actions/security-for-github-actions/security-hardening-your-deployments/configuring-openid-connect-in-pypi

Changelog

Removed the need for static credentials when publishing versions of darwin-py
