repeat_n's documentation lists impl ExactSizeIterator as a difference with repeat + Iterator::take, which is no longer the case

Summary

The newly stabalised std::iter::repeat_n states:

This is very similar to using repeat() with Iterator::take(), but there are two differences:

• repeat_n() can return the original value, rather than always cloning.
• repeat_n() produces an ExactSizeIterator.

But the second item is no longer true, since impl ExactSizeIterator for Take<Repeat<T>> and impl ExactSizeIterator for Take<RepeatWith<F>> now exist and are stable.
