[DocumentIntelligence] DPG: FetchAnalyzeResultFromAnalyzeResultOperation is generated twice

[kinelski]

Code generation is mistakenly creating two copies of the FetchAnalyzeResultFromAnalyzeResultOperation method in DocumentIntelligenceClient, breaking the build.

As a workaround, we're forcibly suppressing their creation with the CodeGenSuppress attribute and adding a manual copy:

azure-sdk-for-net/sdk/documentintelligence/Azure.AI.DocumentIntelligence/src/DocumentIntelligenceClient.cs

Lines 9 to 21 in 0260e01

	[CodeGenSuppress("FetchAnalyzeResultFromAnalyzeResultOperation", typeof(Response))]
	public partial class DocumentIntelligenceClient
	{
	// CUSTOM CODE NOTE: code generation is mistakenly creating two copies of the
	// FetchAnalyzeResultFromAnalyzeResultOperation method, breaking the build.
	// We're forcibly suppressing their creation with the CodeGenSuppress attribute
	// and adding a single copy here.
	private AnalyzeResult FetchAnalyzeResultFromAnalyzeResultOperation(Response response)
	{
	var resultJsonElement = JsonDocument.Parse(response.Content).RootElement.GetProperty("analyzeResult");
	return AnalyzeResult.DeserializeAnalyzeResult(resultJsonElement);
	}

This seems to be a bug in the generator. Once fixed, we need to remove our workaround.

@kinelski is this something we want to create in the autorest repo? /cc: @m-nash
