Support of module pydantic.v1 Since update to Pydantic V2

[Merinorus]

Hello,

Since the V2 update, Pydantic V2 still includes the V1 models to make the migration easier : https://docs.pydantic.dev/latest/migration/#continue-using-pydantic-v1-features

Example :

 from pydantic.v1 import BaseModel

Unfortunately, it seems flask-pydantic dropped the V1 support when it started to support Pydantic V2 (from version 0.12.0). So, if we have to upgrade, we cannot use the pydantic.v1 legacy models with Flask-Pydantic and we have to migrate the whole project's models to Pydantic V2 models directly. Right?
