armadvisor GetGenerateStatus hides relevant HTTP status information

[joshk0]

Bug Report

Package: github.com/Azure/azure-sdk-for-go/sdk/resourcemanager/advisor/armadvisor
SDK version: 1.2.0
Go version: go version go1.21.3 darwin/amd64

• What happened? GetGenerateStatus is a call that tells you whether a recommendation generation operation has completed or not. The HTTP status code is Accepted if the operation is still ongoing and NoContent (204) if the operation has concluded. Otherwise a standard HTTP error. However, the response struct is empty, and will be the same whether 204 or Accepted was returned.
• What did you expect or want to happen? The distinction should be made available via the repsonse struct or an additional return value.
• How can we reproduce it? First, call GenerateRecommendations to get an operation ID (via *resp.Location), then pass it into GetGenerateStatus.
• Anything we should know about your environment. Nothing special
