Describe the bug

Hi, I was upgrading the kratos-client-go SDK version from v0.13.1 to v1.0.0. Upon upgrading, I found a bug regarding the returned struct of the UpdateRegistrationFlow function as it returns nil values.

Reproducing the bug

In the respSubmitFlow , the variable contains nil values. However, on inspecting resp, the body returns the information successfully.

       // ...
       // (usual flow of setting up kratos client)

	respSubmitFlow, resp, err := publicClient.FrontendApi.UpdateRegistrationFlow(ctx).
		Flow(flowId).UpdateRegistrationFlowBody(kratosClient.UpdateRegistrationFlowBody{
		UpdateRegistrationFlowWithPasswordMethod: &kratosClient.UpdateRegistrationFlowWithPasswordMethod{
			Method:   "password",
			Password: "Secured112233445",
			Traits: map[string]interface{}{
				"emails":       []string{email},
				"name_full":    "test namefull",
				"name_display": "test namedisplay",
			}},
	}).Execute()
	if err != nil {
		fmt.Println(err)
		return
	}

Edit: Looks like the decode function could not unmarshal the raw body correctly
