Then after making the changes suggested by the warnings on top

```

Seems like this feature is being deprecated, https://learn.microsoft.com/en-us/azure/aks/use-azure-ad-pod-identity , maybe that's why it doesn't work with Bicep?

### Expected/desired behavior
>
Infra deployed

### OS and Version?
> Windows 7, 8 or 10. Linux (which distribution). macOS (Yosemite? El Capitan? Sierra?)

Tried both, Cloud shell and Az CLI in terminal under win 11

### Versions
>

### Mention any other details that might be useful

To address the podidenity issue

az feature register --name EnablePodIdentityPreview --namespace Microsoft.ContainerService
az provider register -n Microsoft.ContainerService'

Then with that got another error about the AKS version, 1.22.11 no longer supported
