Describe the feature you'd like

Gents,
may be I overlooked, but can you please consider adding .get_models() function to ragflow object in python api?
As per my understanding, it should return list of provider-model names combinations, that user connected to ragflow,
Right now I am thinking only about chat models, but may be we should also pull re-rankers.

It will help to create chat assistant programmaticaly, by iterating through 2-3 most performant model.

Describe implementation you've considered

get_model should return a dict, where key is model type (chat, re-rank, tts, etc), and value is model name
