Apply chat template in mergekit-evolve

[cg123]

Minor update to allow passing apply_chat_template and fewshot_as_multiturn when running mergekit-evolve.

Hi, I have a bug for these two arguments. Could you give me some advice?

I first encountered this problem TypeError: Qwen2ForCausalLM.__init__() got an unexpected keyword argument 'apply_chat_template' .

After I commented out all these relevant config in the code, I got a new issue

File "/opt/conda/envs/python10/lib/python3.10/site-packages/lm_eval/tasks/__init__.py", line 117, in _get_tasklist
   return self.task_index[name]["task"]
KeyError: 'mymodel_evolved'

How can I fix this problem? Thank you!
