chore: Update ruff, mypy and poetry.lock.

[undo76]

Update development dependencies. Also pin litellm to < 1.56.2 until BerriAI/litellm#7583 is solved.

Also included a workaround for this: BerriAI/litellm#7668

Thanks @undo76, those are welcome improvements. Haven’t dug into but could you check why the pipeline is failing?

For some reason the reranker test is failing, maybe we should add more results to prevent "random accidents"

>               assert τ_search >= τ_random >= τ_inverse
E               assert 0.3157894736842105 >= 0.37894736842105264

Also, for python 3.12, there is a problem with llvm_config. Not sure why it happens.
