Consider adding link to Java 8+ Comparators combinators to comparators article

[jafingerhut]

Ghadi Shayban mentioned the addition of these in Java 8: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/Comparator.html

At least adding a link to them would be relatively quick, so more people may learn of them, even if no new text or examples are written on how to use them.

Similar changes could be made to clojure.org guide article on comparators, too, of course.
