Make RedisModel compatible with Pydantic 2.x

[arareko]

This updates RedisModel to use model_config with the right parameters (e.g. from_attributes) instead of the Config class with deprecated attributes (e.g. orm_mode) when Pydantic 2.x is installed. It will most likely resolve the warning shown in #612, but not the main issue reported there.

UserWarning: Valid config keys have changed in V2: * 'orm_mode' has been renamed to 'from_attributes'

I found the above warning while running a FastAPI app in uvicorn within a Python 3.12 virtualenv and the following packages:

This also fixes a few warnings/issues I encountered while testing my changes with make format/lint/test.

i have the exact same problem. this fix works for me 👍

[slorello89]

need to move this import statement, it will break if pydantic v2 isn't present since it's conditionally exporting it in _compat
