Adding roslyn version info in the `dotnet --info` output

[WeihanLi]

Is your feature request related to a problem? Please describe.

It would be easy to know whether the Roslyn's new features are available or not

Describe the solution you'd like

Currently, we already have the MSBuild version, maybe we could add the Roslyn version also

sdk/src/Cli/dotnet/CommandLineInfo.cs

Lines 17 to 25 in a4e5d12

	public static void PrintInfo()
	{
	DotnetVersionFile versionFile = DotnetFiles.VersionFileObject;
	var commitSha = versionFile.CommitSha ?? "N/A";
	Reporter.Output.WriteLine($"{LocalizableStrings.DotNetSdkInfoLabel}");
	Reporter.Output.WriteLine($" Version: {Product.Version}");
	Reporter.Output.WriteLine($" Commit: {commitSha}");
	Reporter.Output.WriteLine($" Workload version: {WorkloadCommandParser.GetWorkloadsVersion()}");
	Reporter.Output.WriteLine($" MSBuild version: {MSBuildForwardingAppWithoutLogging.MSBuildVersion.ToString()}");

Maybe also the nuget client version, could get the nuget client version via dotnet nuget --version now
