November 2022 edition of T297035:
Composer detected issues in your platform: Your Composer dependencies require a PHP version ">= 7.4.3".
Last time, T247653 fixed it when the requirement was PHP >= 7.2.9. The minimum version was bumped, and... here we go again.
Related: https://integration.wikimedia.org/ci/job/mw-tools-phan-demos-publish/266/console (postmerge for phan-taint-check-plugin) also failed to update the demo on doc.wikimedia.org because it requires PHP 7.4, and there it confirms that 7.3.31 is installed.
