Added verification overloading to AnsiConsole.Prompt

[aijkl]

There is a case where we would like to add validation to AnsiConsole.Ask, we have added an overload, please consider merging

        var age = AnsiConsole.Ask<int>("How old are you?", i =>
        {
            return i > 200 ? ValidationResult.Error("Too big.") : ValidationResult.Success();
        });
