Add keep_linebreaks parameter to text loader
Just so I understand how it can be used in practice, do you have an example showing how to load a text dataset with this option? Sure ! Here is an example:
```python
from datasets import load_dataset

load_dataset("text", keep_linebreaks=True, data_files=...)
```

I'll update the documentation to explain this Perfect!
As asked in #870 and https://github.com/huggingface/transformers/issues/10269 there should be a parameter to keep the linebreaks when loading a text dataset.
