python-requests update request

[Adam Dinwoodie]

Hi Marco,

python-requests is currently at v2.27.1, and the latest upstream release
is v2.31.0.  I'm chasing down a long requirement chain as part of trying
to update Cygwin's OfflineIMAP package to run against Python 3, and one
of those requirements wants python-requests to be at least v2.30.0.

I've updated the cygport file for python-requests to compile v2.31.0.
The patch files required some updates to account for changes in the
upstream code, but none of the changes seemed actually significant.
Could you have a look and see if you can upload a new version of
python-requests?

My updated cygport file and patch files are available at
https://github.com/cygporter/python-requests/tree/2.31.0.

Cheers,

Adam
