az network private-endpoint-connection list fails to return Key Vault name attribute for private endpoint

### Describe the bug

The `name` attribute is not returned in the JSON payload much like it is with Storage Accounts or other Azure resources.

azure-cli version `2.56.0`

The JSON payload looks like the following:

```JSON
[
{
"id": "/subscriptions/mySubscriptionID/resourceGroups/myResourceGroupName/providers/Microsoft.KeyVault/vaults/myKeyVaultName/privateEndpointConnections/myKeyVaultPrivateEndpointName",
"properties": {
"privateEndpoint": {
"id": "/subscriptions/mySubscriptionID/resourceGroups/myResourceGroupName/providers/Microsoft.Network/privateEndpoints/myKeyVaultPrivateEndpointName",
"resourceGroup": "myResourceGroupName"
},
"privateLinkServiceConnectionState": {
"actionsRequired": "None",
"status": "Approved"
},
"provisioningState": "Succeeded"
},
"resourceGroup": "myResourceGroupName"
}
]
```

### Related command

az network private-endpoint-connection list -g "ResourceGroupName" -n "KeyVaultName" --type Microsoft.KeyVault/vaults

### Errors

There is no error returned, but the `name` attribute is not returned in the JSON payload much like it is with Storage Accounts or other Azure resources.

### Issue script & Debug output

N/A

### Expected behavior

The JSON should return the `name` attributes of all private endpoints for that queried resource.
