build(deps): upgrade project to support pydantic >= 2

[lf-novelt]

I need to integrate this SDK with FastAPI 0.128 which requires pydantic >= 2

this PR used https://github.com/pydantic/bump-pydantic to perform the migration from v1 to v2

I saw #268 but it's probably more future proof to upgrade at some point

Hey! Sorry to keep you waiting so long. I fixed the local tests because there were some validation errors. But it seems like the tests in CI are not working properly atm. I have to take a look at that and would also need to test it e2e. Does this requirement still exist for you or not? If so, I can continue with it, if not, I would close the pr.

hello, thanks for replying.
yes I still need pydantic >= 2, but I can work with my local fork in the meanwhile.
I guess it won't be long until someone else also needs it. as pydantic v1 will be less and less supported by other libs, so this SDK will become harder to integrate as time goes.
Up to you if worth upgrading I guess :)

Ok great that you have a workaround! We will prioritize this later then, and will keep you in the loop. Thanks for your effort so far!

ok let me check if can make the workflow pass just by updating the PipFile.lock
