Description
When using a la carte imports, I need to import cats.syntax.apply._ to be able to call contramapN, but I expected to import cats.syntax.contravariant._. Here's a scastie to demonstrate: https://scastie.scala-lang.org/mrdziuban/IZmraJ4BRlugdmXfeUWoLg/3

Research direction
Start with the linked Scastie reproduction and trace how contramapN is exposed by the a la carte syntax imports. Check the contravariant and apply syntax entry points; done means importing cats.syntax.contravariant._ alone makes contramapN available.
