decompile does not handle conditional outputs

**Bicep version**
0.4.63

**Describe the bug**
When decompiling a json file with a conditional output, the condition is not transferred, this can cause a deployment to fail if the resource does not exist.

**To Reproduce**
see: https://docs.microsoft.com/en-us/azure/azure-resource-manager/templates/outputs?tabs=azure-powershell#conditional-output

```json
"outputs": {
"fqdn": {
"condition": "[equals(parameters('publicIpNewOrExisting'), 'new')]",
"type": "string",
"value": "[reference(resourceId('Microsoft.Network/publicIPAddresses', parameters('publicIPAddresses_name')).dnsSettings.fqdn]"
}
}
```

Start by reproducing the linked conditional-output example with the Bicep decompiler and trace how ARM JSON outputs are handled. Verify that the output condition is preserved in the decompiled result, then confirm the generated template does not evaluate a reference to a resource that was not deployed.
