### API Spec link

https://github.com/Azure/azure-rest-api-specs/blob/4b57132e90ee9adb1627f27f49d9e960cdeabf37/specification/monitor/resource-manager/Microsoft.Insights/stable/2023-03-11/dataCollectionRules_API.json

### API Spec version

2023-03-11

### Describe the bug

The returned etag is double escaped:
`"etag": "\"uuid\"",`

### Expected behavior

the uuid is not double escaped

### Actual behavior

the etag is double escaped

### Reproduction Steps

GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Insights/dataCollectionRules/{dataCollectionRuleName}?api-version=2023-03-11

### Environment

curl / https://learn.microsoft.com/en-us/rest/api/monitor/data-collection-rules/get?view=rest-monitor-2023-03-11&tabs=HTTP&tryIt=true#code-try-0

Start with the linked Microsoft.Insights dataCollectionRules_API.json specification at version 2023-03-11, then reproduce the documented GET request. Compare the returned etag with the expected UUID representation; the issue is done when the response no longer double-escapes the etag.
