cron format to run at 6 AM on the last Wednesday of the month

[zafarullahdialpad]

Hi, the UNIX CRON does some kind of unexpected disjunctive mapping when the day of the week and day of the month are both specified (restricted). So
0 6 24-31 * 3 will run on every Wednesday and also from 24th to 31st of the month (regardless of the day of the week).

Is there a way to specify last Wednesday of the month using this package?

Context: I am not directly using this package. I am using Kubeflow Pipelines and their documentation point to this package here.

Looks like #325 or #397 would be required to enable the L specifier to get the last day of the month.
