Hello all 👋 - also a newbie to Pulumi. I was able to use it to create an Azure AKS Kubernetes cluster, and also set the kubernetesVersion and update the cluster with pulumi up, but I wasn't able to see how I can set the default nodepool version, which I believe is set independently and e.g. has an azure CLI command to upgrade, but I would like to do this declaratively if at all possible? Thanks.
