[docs] [issue32406] Doc: The new dataclasses module is not documented

[STINNER Victor]

New submission from STINNER Victor <victor.stinner at gmail.com>:

bpo-32214 "Implement PEP 557: Data Classes" added a new dataclasses module and was closed, but the new module is not documented:
https://docs.python.org/dev/library/dataclasses.html

And it's also missing from What's New in Python 3.7:
https://docs.python.org/dev/whatsnew/3.7.html
