SFort (the Fabrication maintainer) is against supporting Modrinth due to their inaccessible "modern" frontend and general "death by a thousand cuts" frustration. New versions of Fabrication & Forgery are no longer published to Modrinth.
You can find current Fabrication downloads on GitHub and CurseForge (Fabrication, Forgery).
