bug: Pydantic feature deprecated, need downgrade on latest pip version

Describe the bug

After a fresh install of openLLM from pip (python 3.12, fresh venv created with virtualfish, pydantic==2.9.0), openllm hello errored with the following message:

AttributeError: module 'pydantic._internal._std_types_schema' has no attribute 'PREPARE_METHODS'

The solution:

pip install --force-reinstall -v "pydantic==2.7.0"

No other versions of pydantic were tried, but openllm hello functions as expected using pydantic==2.7.0

The full error message:

To reproduce

vf new openllm_venv
pip install openllm
openllm hello
