Records packages installed in the project root.

We need to do this before the staging environment has been created, so that we have a complete picture of which requested packages are merely being updated, and which are being newly added. Once the staging environment has been created, the installed packages won't change -- if they do, a validation error will be raised.

Parameters

\Drupal\package_manager\Event\PreCreateEvent $event: The event being handled.

    $event->stage
        ->setMetadata(static::INSTALLED_PACKAGES_KEY, $packages);
