Ambiguous documentation of Sidekiq cron variable

This page says I need to edit the pipeline_schedule_worker_cron value in my gitlab.rb file. Then it points to this page where the same value is called pipeline_schedule_worker.

Which one is the correct name? Also in 'gitlab.rb' file I don't have neither of those, not even commented. So maybe the "edit this value" should be changed to "add this value".
