kubernetes version empty/none #86
Description
I get an empty "kubernetes version" (k8sVersion) within the beiboot object instance after creating an Beiboot cluster using the API when providing no version at all and when providing a specific version (e.g. "1.25.0"). I would expect to always get the version which is used to create the cluster, even if it defaults to a pre-set version. Otherwise it is hard/not possible do return the k8s version to the user via the api.
