Subject: [PATCH 2/2] ci: use ruby/setup-ruby in deploy workflow instead of
 jekyll-build-pages

actions/jekyll-build-pages@v1 bundles sass-3.7.4 which rejects modern
CSS color-function and media-feature-range syntax required by stylelint.
Switch to ruby/setup-ruby with the project Gemfile (Jekyll 4.3) which
ships sass-embedded and handles both correctly.
