Fix release workflow: install dependencies and use modern actions

- Add pip install pyyaml requests before validation
- Replace deprecated actions/create-release@v1 with softprops/action-gh-release@v1
- Use standard GITHUB_TOKEN instead of CONDUCTOR_GITHUB_TOKEN
- Combine asset uploads into single action for efficiency
