DateOnly not supported

The DateOnly data type causes a NotSupportedException to be thrown when calling ParseArguments.

v2.9.1 from Nuget.

public class CommandLineOptions
  {
      [Option('v', "verbose", Required = false, HelpText = "Set output to verbose messages.")]
      public bool Verbose { get; set; }

      [Option('d', "business-date", Required = true, HelpText = "The date (yyyy-mm-dd) to run the process for.")]
      public DateTime Works { get; set; }

      [Option('e', "run-date", Required = true, HelpText = "The date (yyyy-mm-dd) to run the process for.")]
      public DateOnly Fails { get; set; }
  }

Workaround: Use DateTime instead and do an explicit conversion when property is used DateOnly.FromDateTime(value);
