ci: streamline release and publishing process

- Combine tag, release, and publish actions into a single workflow
- Automate CHANGELOG.md updates with each release
- Remove separate release-drafter and python-publish workflows
- Ensure PyPI publishing occurs after successful release creation
- Remove unused release-drafter configuration and workflow

This change improves the automation of our release process,
ensuring consistent versioning, documentation, and distribution
while removing redundant workflows.
