Support multiple cube creators
It seems that Cube Creator has started to support multiple cube creators in the metadata. We should handle this case, as currently we only expect one creator per cube.
This probably will need some thinking, as e.g. now we use creator in the link to OpenDataSwiss, and it's not super clear how we should handle this in case of two creators. Do both of them publish the data on ODS? How to display several links that lead to the same data but published by different creator? These questions need to be answered before we make the switch.

@bprusinowski FYI according to the eCH-0200 v2.0.0 DCAT Application Profile it's mandatory to have exactly 1 dcterms:publisher
- therefore currently no prio
- a next action point will be to rediscuss in context of cube-creator
