cannot update tag on aks 1.11.4 with insights enabled

I wanted to remove one tag from cluster managed with terraform, but it occurred that I cannot because of enabled insights thing on one of clusters. Not sure if only 1.11.4 issue.

I get following error:

```bash
azurerm_kubernetes_cluster.cluster: Error creating/updating Managed Kubernetes Cluster "a-cluster-1" (Resource Group "acc1"): containerservice.ManagedClustersClient#CreateOrUpdate: Failure sending request: StatusCode=0 -- Original Error: Code="LinkedInvalidPropertyId" Message="Property id '' at path 'properties.addonProfiles.omsagent.config.logAnalyticsWorkspaceResourceID' is invalid. Expect fully qualified resource Id that start with '/subscriptions/{subscriptionId}' or '/providers/{resourceProviderNamespace}/'."
```

No repository file, test, or entry point is named. Start by reproducing the Terraform tag update against AKS 1.11.4 with Insights enabled and compare the Azure request; done means removing a tag succeeds without the invalid logAnalyticsWorkspaceResourceID error.
