During the [rollout] of the `explore_groups_vue` feature flag. We've noticed a significant degradation on our API response time after we switched to using `updated_at` as the default sorting option. To get around this, we need to migrate the group list pages to use `created_at` as the default sorting option. This is due to the lack of database index on the `updated_at` column. This is being looked at separately in https://gitlab.com/gitlab-org/gitlab/-/issues/588691+
