Add a new generative model

[YeZiyi1998]

We would like to add Con-J-Qwen2-7B by

python scripts/run_generative.py --model="ZiyiYe/Con-J-Qwen2-7B"

This is our local test results: {'Chat': 0.9189944134078212, 'Chat Hard': 0.7982456140350878, 'Safety': 0.8797297297297297, 'Reasoning': 0.881871692039068} Thanks for your help in advance.
