Unable to load `eli5` dataset with streaming
### Describe the bug

Unable to load `eli5` dataset with streaming.

### Steps to reproduce the bug

This fails with FileNotFoundError: https://files.pushshift.io/reddit/submissions 
```
from datasets import load_dataset
load_dataset("eli5", streaming=True)
```

This works correctly.
```
from datasets import load_dataset
load_dataset("eli5")
```

### Expected behavior

- Loading `eli5` dataset should not raise an error under the streaming mode.
- Or at the very least, show a warning that streaming mode is not supported with `eli5` dataset.
