Add an RSS feed for ESR releases
New /rss/esr/ feed listing the 30 latest ESR releases of all supported ESR branches, linking to their release notes on firefox.com. It shares the releases.rss.twig template with /rss/, whose output is unchanged. The feed is advertised in the page head and on the about page. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
