Add workflow to publish releases to Zenodo

This commit introduces a new GitHub Actions workflow that automates the publishing of releases to Zenodo. The workflow is triggered on the creation of a new release that is not marked as a prerelease. Additionally, it renames the existing publish.yml to publish-pypi.yml for clarity.
