Use rel="noopener" instead of rel="noopener noreferrer" on outbound links - #116

`rel="noopener noreferrer"` strips the Referer header on every outbound link, so traffic this site sends to MapTiler properties arrives as direct and cannot be attributed in MapTiler's reports. `noopener` alone is what the security concern actually needs: it severs `window.opener` on target="_blank" links. `noreferrer` adds nothing there and only suppresses the referrer. Replaced across the 15 files that carried it, including the three literals in _plugins/doclinks.rb — that plugin rewrites every external link in /docs/ pages at build time, so leaving it would keep noreferrer on all 105 generated doclink anchors regardless of the template changes.
