fix: remove @[reducible] attribute from Function.injective (#375) In mathlib3, function.injective is not reducible, so Function.injective should not be reducible here either. To avoid errors in Order/Basic ("@[ext] attribute only applies to structures or lemmas proving x = y"), we need to adjust extAttribute too. Fixes some problems seen in #372.
