Deprecated statements in email.message.rst

Documentation

In https://docs.python.org/3/library/email.message.html

I see:

Unlike a real dict, there is an ordering to the keys

in dictionaries there is no guaranteed order to the keys returned by keys()

But this became false in 3.7 (https://docs.python.org/3/whatsnew/3.7.html « the insertion-order preservation nature of dict objects has been declared to be an official part of the Python language spec »).

I think this can just be removed.

A bit later there's still « in dictionaries there is no guaranteed order to the keys returned by keys() ».
