HelpText different language

Is there a way to make the **HelpText** parameter support a different language at runtime?
example idea, is there an alternative?

```
public class Options
{
public static Localizer _rb;
public ArgOptions(Localizer rb) { _rb = rb; }

[Value(0, Required = true, HelpText = _rb.Get("name"))]
public string? Name{ get; set; }
}
```

The issue names the HelpText parameter, the Value attribute, and a Localizer example but no files or tests. Start by tracing how HelpText is read and rendered for Value arguments, then determine how runtime language selection should work. Done means the behavior and API for displaying HelpText in a different language are defined and covered by appropriate tests.
