Wrong Ollama endpoint

[blakkd]

Describe the bug

From 3.1.0, ollama endpoint seems to be set to [OLLAMA_BASE_URL]/chat/completions instead of /api/chat or /api/generate, resulting in a 404 error.

Rolling back to 3.0.8 with the same .env file restores the correct behavior (connecting to /api/chat).

Doesn't seem related to dd94598.

To Reproduce

git clone https://github.com/assafelovic/gpt-researcher
cd gpt-researcher
pip -r install requirements.txt
python -m uvicorn main:app --reload
