Fix pypi-ci workflow

[Giulero]

This pull request updates the Python packaging and publishing workflow, aligning it with https://packaging.python.org/en/latest/guides/publishing-package-distribution-releases-using-github-actions-ci-cd-workflows/

Copilot summary

CI/CD Workflow Improvements:

• Simplified and restructured the .github/workflows/pypi-ci.yml workflow triggers, ensuring builds run on release, pull request, and workflow dispatch events, and made event types more explicit.
• Refactored job dependencies and artifact naming: standardized the artifact name to dist, set explicit job dependencies using needs, and improved artifact download/upload steps for consistency across jobs.
• Removed the github-release job that signed distributions with Sigstore and uploaded them to GitHub Releases, focusing the workflow solely on PyPI and TestPyPI publishing.

Build System and Publishing Enhancements:

• Updated pyproject.toml to require newer versions of setuptools and setuptools_scm, and removed legacy/duplicate requirements, ensuring compatibility with modern Python packaging standards.
• Added verbose: true and skip-existing: true options to the TestPyPI publishing step, improving feedback and avoiding re-upload errors for existing distributions.

Configuration Improvements:

• Added a [tool.setuptools_scm] section to pyproject.toml to specify local_scheme = "dirty-tag", which controls versioning for local builds.

The condition startsWith(github.ref, 'refs/tags/') will never be true since the workflow no longer triggers on tag pushes. The workflow only triggers on release events, pull requests, and workflow dispatch. Consider removing this redundant condition.
