Describe the bug
OpenAILIKE additional params are not supported like is_chat_model param...

To Reproduce
Configure the following llm module and use is_chat_model param like the following:

    - node_type: generator
      modules:
        - batch: 2
          module_type: llama_index_llm
          llm: openailike
          model: qwen-plus
          is_chat_model: True
          api_base: https://dashscope.aliyuncs.com/compatible-mode/v1
          api_key: x

It will have error like 404 error with the endpoint '/v1/completions'. The error is because is_chat_model param is not passed into the model. If the model itself does not support /v1/completions endpoint, it will have error as it doesn't call /v1/chat/completions'.

Additional context
The root cause may be due to llm_instance params is using llm_class.init instead of the llm_class...

autorag/nodes/generator/llama_index_llm.py line 52 __init__ method

self.llm_instance: BaseLLM = llm_class(**pop_params(llm_class.__init__, kwargs))

When using openAILike, it is converting the OpenAI params with ignoring OpenAILike params....

Possible fix

if llm_class.class_name() == "OpenAILike":
	llm_openaiLike_params = pop_params(llm_class, kwargs)
original_llm_params = pop_params(llm_class.__init__, kwargs)
llm_params = {**llm_openaiLike_params,**original_llm_params}
self.llm_instance: BaseLLM = llm_class(**llm_params)
