Include partial missing from repository

The rewritten About page calls {% include page-author.html %} but the repository (and previous commits) contain no _includes/page-author.html. Jekyll treats missing includes as a fatal build error (Could not locate the included file …), so bundle exec jekyll build and the GitHub Pages pipeline will fail until a partial with that name is added or the include is removed.
