ci: modernize GitHub Pages deployment to use actions/deploy-pages

Replace old branch-based deployment model (JamesIves/github-pages-deploy-action pushing to gh-pages) with the new GitHub Actions deployment model using actions/configure-pages, actions/upload-pages-artifact, and actions/deploy-pages. Rename deploy-docs.yml to deploy.yml.
