Not all progress bars are showing up when they should for downloading dataset
Hi! 

By default, tqdm has `leave=True` to "keep all traces of the progress bar upon the termination of iteration". However, we use `leave=False` in some places (as of recently), which removes the bar once the iteration is over.

I feel like our TQDM bars are noisy, so I think we should always set `leave=False` and also use the `delay` parameter to display progress bars only for tasks that take time (e.g., more than 3s). What do you think about this? Do you find these bars useful (after the dataset generation is over)?
 Hi sorry for the late update. I think the problem still exists despite the `leave` flag

Any idea why this is happening? I debugged this to know the tqdm.pbar value is not being updated properly and its not the kernel not sending the comm messages to the IProgress bar
### Describe the bug

During downloading the rotten tomatoes dataset, not all progress bars are displayed properly. This might be related to [this ticket](https://github.com/huggingface/datasets/issues/5117) as it raised the same concern but its not clear if the fix solves this issue too.

### Steps to reproduce the bug

1. Run this line
```
from datasets import load_dataset

rotten_tomatoes = load_dataset("rotten_tomatoes", split="train")
```

### Expected behavior

all progress bars for builder script, metadata, readme, training, validation, and test set
