When restarting gitlab in puppet, a deprecation warning comes up in the logs:

* gitlab_rails['gitlab_default_can_create_group'] has been deprecated since 15.5 and will be removed in 16.0. Starting with GitLab 15.5, this setting cannot be controlled via the configuration file anymore. Follow the steps at https://docs.gitlab.com/ee/user/admin_area/settings/account_and_limit_settings.html#prevent-users-from-creating-top-level-groups, to configure this setting via the Admin UI or the API

We should update the config file and figure out if we need a way of setting this in puppet instead
