Script raises AttributeError using Pydantic 2.3

[waterfallwhitebread]

Using this script in my project with Pydantic 2.3 (likely all 2.x versions, just tried 2.2 also with same result) with example provided in readme leads to an AttributeError:

C:\SDKs\Python\xxx\Lib\site-packages\pydantic\_migration.py:276: UserWarning: `pydantic.generics:GenericModel` has been moved to `pydantic.BaseModel`.
  warnings.warn(f'`{import_path}` has been moved to `{new_location}`.')

Using Pydantic 1.9 generated correct TS file.
Is this script only supposed to be working with Pydantic 1.x? I didn't see such a limitation in documentation.
Thanks!

There are fixes raised in PRs:

• Updates for newest pydantic #40
• Support for both Pydantic V1 and V2 #38
• Update for pydantic 2 #37

Personally I think this library should be following the versioning strategy of pydantic itself and documented as supporting matching major versions.
