'az backup protection undelete' command fails for AzureStorage type backups

### Describe the bug

The `az backup protection undelete` command is not working as expected for AzureStorage type backups (specifically Azure File Shares). The command executes without error but does not actually perform the undelete operation. The same command works correctly for AzureIaasVM type backups.

### Related command

az backup protection undelete --item-name --resource-group --vault-name --container-name --backup-management-type AzureStorage

az backup protection undelete --ids --backup-management-type AzureStorage

### Errors

No error message is displayed. The command appears to execute successfully, but the backup item remains in a soft-deleted state.

### Issue script & Debug output

az backup protection undelete --item-name "AzureFileShare;df2f837a1cc800d52b230a4fbe0e14313830811814d82562c99d317500d341ca" --resource-group "z-ago-sup-pp55-en1-01" --vault-name "zagosuppp55en1rsv33" --container-name "StorageContainer;storage;z-ago-sup-pp55-en1-01;vzagosup55en1sto33" --backup-management-type AzureStorage --debug

### Expected behavior

The command should initiate the undelete operation for the specified AzureStorage backup item, removing it from the soft-deleted state and making it available for further backup operations.

Your CLI is up-to-date.

### Additional context

1. The same command structure works correctly for AzureIaasVM type backups, suggesting that the issue is specific to AzureStorage type.
2. The Azure portal successfully performs the undelete operation for these items, indicating that the backend API supports this functionality.
3. Debug output shows that the CLI is only making a GET request to retrieve item details, instead of a POST or PUT request to initiate the undelete operation.
3. This issue has been reproduced in multiple environments:
- Azure Cloud Shell
- Ubuntu server
