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.

Reproduce la generación con la especificación Netbox OpenAPI enlazada e inspecciona los modelos generados y models/init.py. Sigue la ruta de generación de modelos para ver cómo se asignan los nombres VLAN y Vlan, y luego añade cobertura que demuestre que tanto los modelos generados como sus importaciones siguen siendo válidos.
