gate-and-submit for change 754495 had four failing jobs: php73-noselenium #45876, php74-noselenium #44397, client #26479, and repo #26475. The first two jobs complain about the xmlwriter extension being missing; the latter two complain about missing dom, intl, mbstring, xml, and xmlreader.
Reason
We have rebuild the CI image for Quibble 1.3.0 which caused a reinstall of the PHP packages. Those come from sury.org. php-xdebug and php-apcu depends on the 8.1 flavor of the package which brings in php8.1-cli but not the other extensions. Essentially the images are broken.
