Describe the bug

There is a bug in the Kratos Golang client, where the oneOf(UiNodeAttributes) is always multiple because they all have node_type This error is being returned https://github.com/ory/kratos-client-go/blob/e9aeb0ece9b90a58659db5287a7d4b895d493209/model_ui_node_attributes.go#L141

This error is discarded too because it swallowed here https://github.com/ory/kratos-client-go/blob/e9aeb0ece9b90a58659db5287a7d4b895d493209/model_ui_node.go#L202-L204

Adding the generator option useOneOfDiscriminatorLookup=true does it correctly.

openapi-generator-cli generate -i api/openapi.yaml -g go --additional-properties="useOneOfDiscriminatorLookup=true"
