karate-robot scroll / pattern support to be added

refer https://stackoverflow.com/a/67608560/143475

would be great if any karate-robot users contribute, this should be very easy following the existing patterns

https://github.com/intuit/karate/blob/v1.0.1/karate-robot/src/main/java/com/intuit/karate/robot/win/Pattern.java#L39

will take time for me as I need to get onto a windows VM
