az connectedk8s enable-features doesn't check if custom-locations-oid input parameter is valid

### Describe the bug

It's an issue related to "az connectedk8s enable-features" Azure client extension
azure client version: 2.58.0 running in an Ubuntu virtual machine in eastus2 region.

The command was used in a virtual machine hosting K3S cluster.

A script called the command line below, though the input parameter custom-locations-oid was incorrect (=4d5bfd0f-2428-4dcb-b8c7-9e439054b9a9), the command didn't raise any error like invalid GUID.

```bash
sudo -u azureuser az connectedk8s enable-features -n vmaio6989devcloudcorp -g rgaio6989devcloud --custom-locations-oid =4d5bfd0f-2428-4dcb-b8c7-9e439054b9a9 --features cluster-connect custom-locations
"Successsfully enabled features: ['cluster-connect', 'custom-locations'] for the Connected Cluster vmaio6989devcloudcorp"
```
Below the command and result with the correct GUID input:
```bash
sudo -u azureuser az connectedk8s enable-features -n vmaio6989devcloudcorp -g rgaio6989devcloud --custom-locations-oid **4d5bfd0f-2428-4dcb-b8c7-9e439054b9a9** --features cluster-connect custom-locations
"Successsfully enabled features: ['cluster-connect', 'custom-locations'] for the Connected Cluster vmaio6989devcloudcorp"
```

Actually, it seems this command 'az connectedk8s enable-features' accepts any string as input parameter without raising any error.
