TODO

• Implement the methods SpecialPageCentralNotice::getShortDescription and SpecialPageCentralNotice::getAssociatedNavigationLinks as in the example in https://gerrit.wikimedia.org/r/c/816211, following the logic in the hook https://gerrit.wikimedia.org/g/mediawiki/extensions/CentralNotice/+/2f02da42d990f4e5596c643721aaf18450482d38/extension.json#315
• Update the hook https://gerrit.wikimedia.org/g/mediawiki/extensions/CentralNotice/+/2f02da42d990f4e5596c643721aaf18450482d38/extension.json#315 to return when Skin::supportsMenu( 'associated-pages' ) is truthy
