Fix missing group 'syself'

It's a good idea to declare a group for related subjects, such as
different regions of the same IaaS product or different k8s versions
of the same KaaS product. Once this change is live on the server,
details for the whole group can be requested under:

https://compliance.sovereignit.cloud/page/detail_full/group-syself/1fffebe6-fd4b-44d3-a36c-fc58b4bb0180

It will be similar to this page:

https://compliance.sovereignit.cloud/page/detail_full/group-pco-prod/50393e6f-2ae1-4c5c-a62c-3b75f2abef3f
