jobs/seed: set git credentials to admin_credentials and remove doc job

On the HAC instance, we currently do not want the documentation
job of the work of Marc Mattmueller, thus this job is removed.
Additionally the git credential ID differs between HAC- and ansible
instance. Therefore we set on this branch the credentials of the
HAC instance.
