Remove `[www.]creativecommons.dk` web forwarding

Description

The domain creativecommons.dk and www.creativecommons.dk, currently hosted on puntum.dk, is no longer managed by Creative Commons. To streamline operations and avoid unnecessary alerts, we are removing it from creativecommons/sre-salt-prime repository. If we manage it in the future, we will use our domain provider’s web forwarding
