"""Shim to allow support for both Pydantic 1 and Pydantic 2.

dbt-core must support both major versions of Pydantic because dbt-core users might be using an environment with
either version, and we can't restrict them to one or the other. Here, we essentially import all Pydantic objects
from version 1 that we use. Throughout the repo, we import these objects from this file instead of from Pydantic
directly, meaning that we essentially only use Pydantic 1 in dbt-core currently, but without forcing that restriction
on dbt users. The development environment for this repo should be pinned to Pydantic 1 to ensure devs get appropriate
type hints.
