ORES now supports topic prediction (`articletopic`). Topic prediction is different than class prediction and potential issue prediction. Topic prediction means predicting if an article is about chemistry, politics and government, sports, Central Asia, etc.
New page patrollers would find this useful if they want to filter the feed by one or two topics that they are interested in or have specialized knowledge in. Currently other tools are used to do this, such as
https://en.wikipedia.org/wiki/User:SDZeroBot/NPP_sorting, which I believe uses the exact same ORES model but is not integrated into PageTriage.
This ticket is to integrate `articletopic` into PageTriage, in both the Special:NewPagesFeed filters menu, and the Page Curation toolbar "Page info" flyout.
