Update Certutil.yml with new flag and update previous flag

Added the '-URL' argument which allows for downloads through a GUI for which credit goes to @Hexacorn  (https://www.hexacorn.com/blog/2020/08/23/certutil-one-more-gui-lolbin/)

removed the '-split' flag from the existing '-urlcache' command as it is not actually required and makes the detections too narrow
