I'd like to have the extension "wikidiff2" (version 1.9) installed on the Docker image that runs the project "mediawiki/tools/api-testing". Job name is "mediawiki-quibble-api-testing-vendor-mysql-php72-docker".
This is due to a new endpoint in mediawiki core (T231580) that requires the wikidiff2 extension > version 1.9. The extension can be found in the Wikimedia Debian apt repository.
Please let me know if any of this is unclear!
