chore(deps): re-add dragonmantank/cron-expression for the scheduler

This dep was silently dropped by the earlier `composer require
symfony/mercure-bundle --no-scripts` on the prod host (it ran in
no-dev mode and removed packages not currently referenced in
require/require-dev), which crash-looped the worker when
Symfony\Component\Scheduler\Trigger\CronExpressionTrigger tried to
parse the hourly RunImageCleanupMessage cron.
