Add Pydantic >2 support.

[hcrosse]

This project is currently bound by pydantic >= 1.10.5, < 2. The OpenAPI Generator >=v7.4.0 (and maybe >=7.1.0) supports pydantic >2. This limitation is causing me to have to fall back to using vanilla requests instead of using this SDK due to conflicting dependencies.

Thanks in advance!

We are having the same issue here. Is this possible to have addressed?

Same here, urllib3 and pydantic are way outdated, rendering the SDK useless.
