CAUTION:
It looks like you have just added new secret(s) #{new_secrets.inspect} to the secrets.yml.
Please read the development guide for GitLab secrets at doc/development/application_secrets.md before you proceed this change.
If you're absolutely sure that the change is safe, please add the new secrets to the 'acknowledged_secrets' in order to silence this warning.
