ci: use Python 3.10 in linting & testing

[ErikBjare]

As requested in #898 (comment)

Build will fail and linters will scream until the occurrences of type1 | type2 is replaced with Union[type1, type2].

Waiting for @similato87 to make the changes requested in #898 (comment)

• Apply: Ensure all new functions and classes have very clear, concise and up-to-date docstrings. Take gpt_engineer/ai.py as a good example.

Thanks @ErikBjare .
Do we need to make an explicit local rebase for checks to pass or is there an easier way?

@ATheorell @similato87 There are more changes needed to make it supported on Python 3.8. See the failing CI log.

Mainly that things like tuple[int, int] needs to be Tuple[int, int] (default collections became types when subscripted in 3.9, they need their types imported from typing in 3.8).

I've noticed the need for additional syntax adjustments to ensure Python 3.8 compatibility. I'm setting up a Python 3.8 environment to accurately test these changes, and then I'll proceed to update the type hinting throughout the codebase to make it fully compatible with Python 3.8.

Hi @ErikBjare , I finished refactored and created the new PR: #910

[ErikBjare]

There seems to be even more changes needed for 3.8 & 3.9 support.

Given the decision to bump the lowest supported version to 3.10, I will modify this PR to target 3.10 instead and get it merged.
