Use myst build and gh-pages deployment like us-data

- Use myst build --html instead of jupyter book build
- Set BASE_URL=/policyengine-uk-data for correct GitHub Pages paths
- Create .nojekyll file in build output
- Deploy to gh-pages branch using JamesIves/github-pages-deploy-action
- Fix author name format in myst.yml to avoid warnings
- Matches working policyengine-us-data deployment pattern
