Mention SliceConcatExt's stability in its docs
SliceConcatExt's status as an unstable trait with stable methods is documented in the compiler error for using it, and in https://doc.rust-lang.org/std/prelude/, but it is not mentioned in the trait itself. Mentioning the methods can be used in stable rust today should help users who are looking for a `join` method while working on stable rust.
