Run CI for Python 3.13

[jakob-keller]

Description of Change

Python 3.13 is being finalized and the final beta has just been released:

We strongly encourage maintainers of third-party Python projects to test with 3.13 during the beta phase...

Note: This PR neither drops support for Python 3.8 not does it declare support for Python 3.13, i.e. in docs or PyPI trove classifiers. Both should be addressed separately, preferable around the time the final version of Python 3.13 is released.

Assumptions

Compatibility of aiobotocore with Python 3.13 should be tested ahead of its final launch.

A number of tests are failing. I believe there are several underlying issues with dependencies, including python-cffi/cffi#77. I will retry as soon as those are resolved.

bonus points for tackling latest moto too. I pushed a branch with the changes required to get it running

https://github.com/python-cffi/cffi/releases/tag/v1.17.0rc1 mentions Python 3.13. How about temporarily using cffi==1.17.0rc1 in CI?

as noted in other pr, changes for moto 5.x here: https://github.com/aio-libs/aiobotocore/compare/thehesiod/aio-checksum-streaming-moto-bump
