Currently, article pages contain the JSON-LD linked data schema at the bottom of the article page. Calling this method triggers two DB queries to fetch the description of the entity and the first revision of the article.

Building the JSON-LD schema takes around 5% of the request time for an article. (https://performance.wikimedia.org/excimer/profile/17c43b402fb432bb). We should look into caching the result of TermLookup::getDescription and RevisionLookup::getFirstRevision as there is no need to execute these every request.
