Update Sphinx workflow for GitHub Pages deployment

Enhance Sphinx GitHub Actions workflow

- Use ubuntu-latest runner instead of ubuntu-24.04-arm for wider support
- Add Python dependency caching for faster builds
- Add descriptive step names for better readability in CI logs
- Keep minimal required permissions for improved security
- Maintain concurrency to prevent overlapping deployments
