python: Fix minimum version for pydantic

[svix-jplatte]

We are using ModelWrapValidatorHandler, which was introduced in 2.10

Also add maximum versions because it seems wrong that we don't have them.

@svix-jplatte Just ran into this in my application today so I've pinned svix to 16.2.0. Do we also need to declare pydantic > 2.10 in the setup.py file so pip is aware of this requirement?

I'm stuck on pydantic 2.9.2 until I update my application for compatibility with 2.10 so when I upgrade svix to 16.4.0 my application started failing.

You shouldn't have to declare pydantic > 2.10 yourself, no. I was not aware that 2.10 contains breaking changes, that's unfortunate. I hope it's not much of an issue for you to pin the svix dependency.

@svix-jplatte Sorry the suggestion was for svix to declare pydantic>2.10 in the setup.py file so pip could handle this requirement successfully. Regardless, pinning svix on my end is successful.

Appreciate the package, thank you for your time.

Cheers!

Oh, that's a good point. We probably should, I'll send a PR!
