Decompiler is not aware, that @description is allowed on outputs

Bicep version
Bicep CLI version 0.4.613 (d826ce8)

Describe the bug
Since PR 4091 #4091 the Outputs support the @description('my description') decorator. If you build a bicep file with that, it creates the "metadata": {"description": "value"} in the json file. But if you go the other way round and decompile the json file, which has the metadata declared for an output, it does not create the @description in the bicep file.

To Reproduce
1.) create json with an output, like:

"outputs": {
        "virtualMachinesResourceGroup": {
            "type": "string",
            "value": "[resourceGroup().name]",
            "metadata": {
                "description": "The name of the Resource Group the VM(s) was/were created in."
            }
        }
    }

2.) run bicep decompile xxx.json

3.) look at the created bicep file in the output section, there is the output but no description on it
