Description

PYPI now has pydantic at 2.x and having two versions of Pydantic at the same time causes conflicts in resolving dependencies for some other packages, because pydantic-1.x and pydantic-2.x use the same namespace 'pydantic'.

I am trying to create the FreeBSD port for FreqTrade https://www.freqtrade.io/, but it requires pydantic-2.x, but FastAPI is one of its dependencies, and it requires pydantic-1.x

2 versions of the same package can't exist simultaneously in the same environment.

The version of FastAPI that you're using supports using Pydantic 2.x https://github.com/tiangolo/fastapi/blob/040ad986d48bb9a400de804f7f25abb856d85e1a/pyproject.toml#L44
