Suggestions don't work when tool is invoked as a dotnet subcommand

[tmds]

I have a tool named dotnet-shift.

The tool can either be invoked as dotnet-shift, or it can be invoked as dotnet shift.

When the former syntax is used to invoke the tool, the command completions work.
And when the latter is used, they don't.

My understanding is that for this to work, the .NET SDK should pass on the request for suggestions to the tool that gets invoked.

This is a very old issue (#343) which I suspect can be addressed in the shim scripts.

@jonsequitur there is some code here:

command-line-api/src/System.CommandLine.Suggest/SuggestionDispatcher.cs

Lines 198 to 201 in 87704ce

	if (fileNameWithoutExtension?.StartsWith("dotnet-", StringComparison.Ordinal) == true)
	{
	yield return "dotnet " + fileNameWithoutExtension.Substring("dotnet-".Length);
	}

This doesn't do anything meaningful for bash, does it make something work for the other shells?
