Log Message:
py-aiohttp: updated to 3.8.3

3.8.3 (2022-09-21)
==================

   This is the last :doc:`aiohttp <index>` release tested under
   Python 3.6. The 3.9 stream is dropping it from the CI and the
   distribution package metadata.

Bugfixes
--------

- Increased the upper boundary of the :doc:`multidict:index` dependency
  to allow for the version 6 -- by :user:`hugovk`.

  It used to be limited below version 7 in :doc:`aiohttp <index>` v3.8.1 but
  was lowered in v3.8.2 via :pr:`6550` and never brought back, causing
  problems with dependency pins when upgrading. :doc:`aiohttp <index>` v3.8.3
  fixes that by recovering the original boundary of ``< 7``.
