Support Pydantic v2

[srhinos]

Pydantic has gone live with their new version

Being that its production ready and as suggested by Pydantic's README:

Pydantic V2 also ships with the latest version of Pydantic V1 built in so that you can incrementally upgrade your code base and projects: from pydantic import v1 as pydantic_v1.

It should be safe to upgrade and allow folks using poetry (like me) to resolve dependancies in a way that unblocks upgrading to Pydantic v2, FastAPI v0.100.0, etc
