Describe the bug

When using the ListAsync method of the ReaderService, an ArgumentOutOfRangeException is thrown by the Stripe.Infrastructure.UnixDateTimeConverter.ReadJson method. I believe the issue is being caused by the last_seen_at field, which comes back as a unix timestamp in milliseconds, however, the converter expects seconds. The same error is thrown when using the GetAsync method of the same service.

I'm using version 49.2.0 with .NET 8.

To Reproduce

var service = new ReaderService();
var requestOptions = new ReaderListOptions
{
    Limit = 1,
    Status = "online"
};
var readers = await service.ListAsync(requestOptions, cancellationToken: cancellationToken);

Expected behavior

The ListAsync method should return a list of readers, not throw an exception.
