Fix GitHub Pages deployment workflow

- Update upload-pages-artifact from v3 to v4 for compatibility
- Add configure-pages action for proper Pages setup
- Ensure artifact upload works with deploy-pages@v4
- Resolves 'No artifacts named github-pages were found' error

The workflow now properly:
- Configures GitHub Pages environment
- Builds MkDocs documentation
- Uploads Pages artifact correctly
- Deploys to GitHub Pages
