Make connectors work with python 3.10 and 3.11

[artem-shelkovnikov]

Part of #2672

This PR makes connectors work with 3.10 and 3.11 version of Python. 3.12 is not supported yet because of some deprecations for datetime package that we need to handle: https://blog.miguelgrinberg.com/post/it-s-time-for-a-change-datetime-utcnow-is-now-deprecated. Once it's handled, adding 3.12 to matrix is gonna be trivial.

CI image was updated to make it work, here's the CI image script: https://github.com/elastic/ci-agent-images/blob/main/vm-images/enterprise-search/scripts/connectors-python/install-deps.sh

It's just a random blip from CI not being able to start Elasticsearch, feel free to review :)

few comments/questions, but looks pretty straightforward, honestly. Nice work!

I kicked off a nightly, just for a double check: https://buildkite.com/elastic/connectors-nightly/builds/2404

also, realized that 3.12 had slipped through in a few places

this change requires your setup to have an alias for python, in my machine I didn't had that and to make it work I have to do PYTHON=python3 make install

Is this an issue ? If no do we want to mention it in somewhere?
