fix(aks): update example & instructions to create successful clusters

[metral]

dupe: #1037 - but #1037 was messed up due to accidentally merging in master into the PR branch, creating a large, useless commit, so this PR is being created on the most recent master, in its replacement

related:

• Getting an intermittent failed to refresh Bearer token error when trying to delete my AKS cluster hashicorp/terraform-provider-azurerm#2602 (comment)
• Token expires during longer Pulumi programs pulumi-azure#217

🍹 The Update (preview) for stack pulumi/pulumi.io/pulumi.io-staging was successful.
