Official support for Python 3.11 and Python 3.12?

AWS Lambda officially supports Python 3.11 and Python 3.12.

Would it be possible to test this library against those 2 new versions of Python?
From the setup.py it looks like there is no constraint preventing us from using it with runtimes higher than 3.10, however it's not tested.

The tests are failing in the Github actions because of 3.7 and the linting steps. I forked and added 3.11 and 3.12 to the test.yml, and commented out the previous two, and they passed.

Added explicit support to Python 3.13. 👍
