Add GitHub Actions workflow for deploying to GitHub Pages

- Create a new workflow file `gh-pages.yml` to automate deployment to GitHub Pages.
- Set up steps for checking out the repository, installing `uv`, setting up Python, installing dependencies, building the site with MkDocs, and deploying the built site.
- Ensure the workflow triggers on pushes and pull requests to the main branch.
