Validation is not invoked when IRequest has no Result

[Balirezaei]

Hi
In Dot Net SDK 8
MediatR 12.2

This code is working properly
`

public class UpdateTodoListCommandValidator : AbstractValidator<UpdateTodoListCommand>
{
    public UpdateTodoListCommandValidator()
    {
        RuleFor(v => v.Title)
            .NotEmpty()
            .MaximumLength(200);
    }
}

public record UpdateTodoListCommand : IRequest<int>
{
    public int Id { get; init; }

    public string? Title { get; init; }
}

public class UpdateTodoListCommandHandler : IRequestHandler<UpdateTodoListCommand,int>
{
    public async Task<int> Handle(UpdateTodoListCommand request, CancellationToken cancellationToken)
    {
        return 1;
    }
}

`

but when we remove the Irequest Result (In this example (int)) Validation is not fired.

Kind regards and thanks for a fantastic free tool.
