[BUG] `automation`: Runtime Environment Package GET API missing contentLink properties

API Spec link

https://github.com/Azure/azure-rest-api-specs/blob/main/specification/automation/resource-manager/Microsoft.Automation/stable/2024-10-23/package.json

API Spec version

2024-10-23

Describe the bug

When creating a Runtime Environment Package resource (Microsoft.Automation/automationAccounts/runtimeEnvironments/packages) with contentLink field (including uri, version, and contentHash), the GET API does not return these fields in the response.

This is the same issue as #25538 (which reports the problem for python3Packages) but now also affects the newer runtimeEnvironments/packages resource introduced in api-version 2024-10-23.

Expected behavior

The GET API should return the contentLink field with uri, version, and contentHash properties that were provided during resource creation.

Actual behavior

The contentLink field is completely absent from the GET response, even though it was provided during creation.

Reproduction Steps

1. Create a Runtime Environment Package with contentLink:

PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Automation/automationAccounts/{automationAccountName}/runtimeEnvironments/{runtimeEnvironmentName}/packages/{packageName}?api-version=2024-10-23

{
  "properties": {
    "contentLink": {
      "uri": "https://pypi.org/packages/source/r/requests/requests-2.31.0.tar.gz",
      "version": "2.31.0",
      "contentHash": {
        "algorithm": "sha265",
        "value": "07E108A962B81DD9C9BAA89BB47C0F6EE52B29E83758B07795E408D258B2B87A"
      }
    }
  }
}

2. Wait for provisioningState to become Succeeded.
3. GET the package:
   GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroup}/providers/Microsoft.Automation/automationAccounts/{automationAccountName}/runtimeEnvironments/{runtimeEnvironmentName}/packages/{packageName}?api-version=2024-10-23
4. Observe that contentLink is missing from the response properties.

Environment

No response

Start with the 2024-10-23 specification/automation/resource-manager/Microsoft.Automation/stable/2024-10-23/package.json API definition linked in the issue. Compare the Runtime Environment Package create and GET shapes, then validate the specification; done means GET responses expose the submitted contentLink, including uri, version, and contentHash.
