"--version option cannot be combined with other arguments." is not displayed when "--help" is also specified

Hi.

Thank you for System.CommandLine.

The error message "--version option cannot be combined with other arguments." is not displayed when "--help" is also specified on the command line.

Steps to reproduce:

1. Build console app with Program.cs:
```
internal class Program
{
static async Task Main(string[] args)
{
RootCommand rootCommand = new RootCommand();

var option = new Option("--option1");

rootCommand.Add(option);

rootCommand.Handler = CommandHandler.Create(() =>
{
Console.WriteLine("Hello, World!");
});

return await rootCommand.InvokeAsync(args);
}
}
```

2. Run `ConsoleApp1.exe --option1 --version`
Notice the error `--version option cannot be combined with other arguments.`
This is expected behavior.

3. Run `ConsoleApp10.exe --help --version`
Notice the error is not displayed.
Only the version is displayed.
This is unexpected behavior; I expected the error `--version option cannot be combined with other arguments.`.

4. Run `ConsoleApp10.exe --option1 --help --version`
Notice the error is not displayed.
Only the version is displayed.
This is unexpected behavior; I expected the error `--version option cannot be combined with other arguments.`.

Thank you.

Inizia con la riproduzione in Program.cs ed esegui le combinazioni di comandi --help/--version elencate per confermare le differenze nell’output. Poi traccia come la CLI gestisce gli argomenti di help e versione; il lavoro è concluso quando viene visualizzato l’errore previsto "--version option cannot be combined with other arguments." quando vengono fornite entrambe le opzioni.
