Redis-OM JsonModel subclasses BaseModel but does not use type hints in method arguments popup

[b-kuch]

Describe the bug
Redis-OM JsonModel __init__ does not take advantage of type hints even though it subclasses pydantic BaseModel.

To Reproduce
Steps to reproduce the behavior:

1. pip install redis_om
2. Create class as on screen.
3. Check the inspection on __init__.

Expected behavior
Type hints are used in method parameter popup.

Screenshots
Popup uses type hints when it subclasses BaseModel:

But doesn't when it subclasses JsonModel:

Environments (please complete the following information):

• IDE: PyCharm 2021.3.3
• OS: Windows10
• Pydantic Version 1.9.0
• Plugin version 0.3.12

Additional context
JsonModel implements __init__ so I tried to follow solution shown in #344 but it was to no avail.
