[issue45090] Add pairwise to What's New in Python 3.10; mark it as new in itertools docs

[Luciano Ramalho]

New submission from Luciano Ramalho <luciano at ramalho.org>:

Thanks for adding `itertools.pairwise()`!

Let's make it easier to find by mentioning it in "What's New in Python 3.10" and also marking it as "New in Python 3.10" in the `itertools` module documentation.
