[Feature Request]: Reduce the wrapping around SDK Resolver messages when only one resolver is actually invoked

[baronfel]

Summary

In dotnet/sdk#41268 I was able to use the SDK Resolver features to ensure that only the NuGet SDK resolver was used for a restore. In this case we should be able to remove MSBuild wrapping around the 'error list' and only surface the single Resolver's message.

Background and Motivation

We want to remove visual noise around error experiences and make it easier for users to diagnose the core problems.

Proposed Feature

msbuild/src/Build/BackEnd/Components/SdkResolution/SdkResolverService.cs

Lines 277 to 280 in 0032522

	if (failOnUnresolvedSdk)
	{
	loggingContext.LogError(new BuildEventFileInfo(sdkReferenceLocation), "FailedToResolveSDK", sdk.Name, string.Join($"{Environment.NewLine} ", errors));
	}

should change the way it logs to not log the wrapper if only one resolver was used.

Makes sense to me. A small change in logging.
