docs(orderBy): Start with a simpler example.

Per the question raised at this Stack Overflow question:
http://stackoverflow.com/questions/24048590/angularjs-ng-repeat-orderby-date-not-working

The first example on this page is too complex to convey
the simplest possible case for using this function.

Closes #11144
