ruff failed

rivery_scim_client/models/book.py:40:21: F821 Undefined name cast Found 209 errors (208 fixed, 1 remaining).

As you can see there is an import missing. I publish a PR that should solve it. https://github.com/openapi-generators/openapi-python-client/pull/1072

OpenAPI Spec File I created a dummy openapi specification.
