Update python3-aiohttp-utils to 3.2.x
Version 3.2.0 (well, 3.2.1) adds support for Python 3.11: https://github.com/sloria/aiohttp-utils/blob/master/CHANGELOG.rst#321-2023-02-14
This should unblock Debian builds of python3-swh.core (https://jenkins.softwareheritage.org/job/debian/job/packages/job/DCORE/job/gbp-buildpackage/263/consoleFull)
