 Add a caveat to the GHC.Generics examples about :+: nesting

 Summary:
 GHC's choice in how it nests `:+:` can sometimes affect the
 implementaiton of `GHC.Generics`-related code, so we should make a note of
 this in the examples we provide. Fixes #9453.

 Test Plan: Read it, like it, build it, ship it
