Azure connected clusters fails, unable to connect cluster to Azure via arc as part of IoT Ops setup

### Describe the bug

Attempting to connect a cluster via connectedk8s as part of the Azure IoT Ops suite I'm getting stuck when connecting my local k3s cluster to Azure Arc.

### Related command

```
az connectedk8s connect -g -n -l westeurope --subscription --tags System.Object[] --disable-auto-upgrade --enable-oidc-issuer --enable-workload-identity
```

Same error with:
```
az connectedk8s connect -g -n -l westeurope --subscription --tags System.Object[] --disable-auto-upgrade
```

### Errors

``` Preview version of extension is disabled by default for extension installation, enabled for modules without stable versions.
