Remove default trust remove code for predefined datasets

[echarlaix]

Removing trust_remote_code=True when loading a dataset from PREDEFINED_SD_DATASETS :

• conceptual_captions
• laion/220k-GPT4Vision-captions-from-LIVIS
• laion/filtered-wit

for now loading automatically the dataset conceptual_captions when specified in the quantization config will fail as trust_remote_code=True is needed for datasets with a python loading script for datasets>=v2.20.0

I opened https://huggingface.co/datasets/google-research-datasets/conceptual_captions/discussions/3 to not require trust_remote_code on conceptual_captions
