Elan → Stratego in documentation of `rewrite_strat`.

@eelcovisser told me that the strategies in Luttik and Visser 97 were inspired
by Elan, but they are not part of Elan. They are part of the Stratego language.

 The generalized rewriting tactic is based on a set of strategies that can be
 combined to obtain custom rewriting procedures. Its set of strategies is based
-on Elan’s rewriting strategies :cite:`Luttik97specificationof`. Rewriting
