jsonlines files don't load with `load_dataset`
### Describe the bug

While [the docs](https://huggingface.co/docs/datasets/upload_dataset#upload-dataset) seem to state that `.jsonl` is a supported extension for `datasets`, loading the dataset results in a `JSONDecodeError`.

### Steps to reproduce the bug

Code:
```
from datasets import load_dataset
dset = load_dataset('slotreck/pickle')
```

Traceback:
```
