The commit adds "associated" to the description of associated types and associated consts, to match the description of associated functions. This increases error message precision and consistency with `AssocKind::fmt`. The commit also notes an imperfection in `AssocKind::fmt`; fixing this imperfection is possible but beyond the scope of this PR.
