Packaging script information missing

That information is added in the archive files created by the packaging script running on drupal.org.

# Information added by Drupal.org packaging script on 2023-10-25

The .info.yml file committed in the repository does not contain those lines. Project maintainers do not need to add them, as the packaging script will add them, but in the archive files containing the project files.
