Issue: Pushing dataset to hub crash
State: closed

### Describe the bug

Uploading a dataset with `push_to_hub()` fails without error description. 

### Steps to reproduce the bug

Hey there,

I've built a image dataset of 100k images + text pair as described here https://huggingface.co/docs/datasets/image_dataset#imagefolder

Now I'm trying to push it to the hub but I'm running into issues. First, I tried doing it via git directly, I added all the files in git lfs and pushed but I got hit with an error saying huggingface only accept up to 10k files in a folder.

So I'm now trying with the `push_to_hub()` func as follow:

```python
from datasets import load_dataset
import os

dataset = load_dataset("imagefolder", data_dir="./data", split="train")
dataset.push_to_hub("tzvc/organization-logos", token=os.environ.get('HF_TOKEN'))
```

But again, this produces an error:

```

What could be happening here ?

### Expected behavior

The dataset is pushed to the hub

### Environment info

- `datasets` version: 2.10.1
- Platform: Linux-5.10.0-21-cloud-amd64-x86_64-with-glibc2.31
- Python version: 3.9.2
- PyArrow version: 11.0.0
- Pandas version: 1.5.3

Hi ! It's been fixed by https://github.com/huggingface/datasets/pull/5598. We're doing a new release tomorrow with the fix and you'll be able to push your 100k images ;)

Basically `push_to_hub` used to fail if the remote repository already exists and has a README.md without dataset_info in the YAML tags.

In the meantime you can install datasets from source

Hi @lhoestq ,

What version of datasets library fix this case? I am using the last `v2.10.1` and I get the same error.

We just released 2.11 which includes a fix :)
