Add GitHub Actions workflow for Quarto site deployment

Add GitHub Actions CI/CD workflow that automatically renders the Quarto website and deploys it to GitHub Pages whenever changes are pushed to the repository.

The workflow:
- Spins up an Ubuntu runner
- Installs R 4.4.0 and required packages (leaflet, base64enc)
- Installs Quarto
- Renders the site with `quarto render`
- Commits and pushes the updated `docs/` folder back to the repository

This allows contributors to add or edit .qmd files directly on GitHub.com without needing a local R/Quarto installation.
