feat: AnnotatorInterFace add Auto Train config on dataset creation

[davidberenstein1957]

Per task, we might be able to upload config to directly try out and fine-tune with annotated examples.

"we haven't done it yet but cool idea. we can upload autotrain_config.yaml or something like that in the same format as example configs here: https://github.com/huggingface/autotrain-advanced/tree/main/configs. users can then just point to the config yaml link in autotrain --config https://config.url/"
