CodeActionHandler.cs: FileNotFoundException when using inmemory: protocol

[dkattan]

In WorkSpaceService.cs

PowerShellEditorServices/src/PowerShellEditorServices/Services/Workspace/WorkspaceService.cs

Lines 193 to 197 in a12edc9

	// List supported schemes here
	case "file":
	case "untitled":
	case "vscode-notebook-cell":
	break;

Consider adding

case: "inmemory":

as this is the default for the MonacoLanguageClient

Additionally for this to work, consider the following change to prevent a FileNotFoundException in CodeActionHandler.cs

PowerShellEditorServices/src/PowerShellEditorServices/Services/TextDocument/Handlers/CodeActionHandler.cs

Line 60 in a12edc9

IReadOnlyDictionary<string, MarkerCorrection> corrections = await _analysisService.GetMostRecentCodeActionsForFileAsync(

IReadOnlyDictionary<string, MarkerCorrection> corrections = null;
try
{
    var file = _workspaceService.GetFile(request.TextDocument.Uri);
    corrections = await _analysisService.GetMostRecentCodeActionsForFileAsync(file).ConfigureAwait(false);
}
catch (Exception ex) //if (corrections == null)
{
    return Array.Empty<CommandOrCodeAction>();
}

This seems reasonable to do. Any reason in particular you didn't open a PR for these changes (or those in #1495)?
