Conflicting module names for models silently generate invalid code

Describe the bug

I am generating a Python Client using the OpenAPI model of Netbox 3.6.9 (with a few plugins pre-installed).
This schema contains for example a model VLAN and a model Vlan.

However, in the generated client, only the model Vlan is generated, but the models/__init__.py still tries to import VLAN.

OpenAPI Spec File

https://gist.github.com/linkdd/3193453b38357d190545c7988cdac692

Desktop:

• OS: Debian 12
• Python Version: 3.12
• openapi-python-client version 0.21.6

Additional context

At $day_job, it was a blocking point, we had to remove temporarily the dependency to the generated client. I added a few tasks to my backlog in order to tackle this issue myself and ideally come up with a PR, but it won't be soon. Any help or information on how/where the model generation actually happens would be awesome and a huge time saver.

Reproduisez la génération avec la spécification Netbox OpenAPI liée et examinez les modèles générés ainsi que models/init.py. Suivez le chemin de génération des modèles pour voir comment VLAN et Vlan sont nommés, puis ajoutez une couverture montrant que les modèles générés et leurs imports restent tous deux valides.
