Broken Image render on the hub website
### Describe the bug

Hi :wave: 

Not sure if this is the right place to ask, but I am trying to load a huge amount of datasets on the hub (:partying_face: ) but I am facing a little issue with the `image` type

![image](https://user-images.githubusercontent.com/15908060/228587875-427a37f1-3a31-4e17-8bbe-0f759003910d.png)

See this [dataset](https://huggingface.co/datasets/Francesco/cell-towers), basically for some reason the first image has numerical bytes inside, not sure if that is okay, but the image render feature **doesn't work**

So the dataset is stored in the following way

```python
    builder.download_and_prepare(output_dir=str(output_dir))

    ds = builder.as_dataset(split="train")
    # [NOTE] no idea how to push it from the builder folder
    ds.push_to_hub(repo_id=repo_id)
    builder.as_dataset(split="validation").push_to_hub(repo_id=repo_id)
    ds = builder.as_dataset(split="test")
    ds.push_to_hub(repo_id=repo_id)
   ```
   
   The build is this class
   
   ```python
       class COCOLikeDatasetBuilder(datasets.GeneratorBasedBuilder):

        VERSION = datasets.Version("1.0.0")

        def _info(self):
            features = datasets.Features(
                {
                    "image_id": datasets.Value("int64"),
                    "image": datasets.Image(),
                    "width": datasets.Value("int32"),
                    "height": datasets.Value("int32"),
                    "objects": datasets.Sequence(

                            "category": datasets.ClassLabel(names=categories),
                        }
                    ),
                }

            idx = 0

```

Basically, I want to add to the hub every dataset I come across on coco format

Thanks

### Steps to reproduce the bug

In this case, you can just navigate on the [dataset](https://huggingface.co/datasets/Francesco/cell-towers)

### Expected behavior

I was expecting the image rendering feature to work

### Environment info

Not a lot to share, I am using `datasets` from a fresh venv
Hi! 

You can fix the viewer by adding the `dataset_info` YAML field deleted in https://huggingface.co/datasets/Francesco/cell-towers/commit/b95b59ddd91ebe9c12920f0efe0ed415cd0d4298 back to the metadata section of the card. 

To avoid this issue in the feature, you can use `huggingface_hub`'s [RepoCard](https://huggingface.co/docs/huggingface_hub/package_reference/cards) API  to update the dataset card instead of `upload_file`:
```python
from huggingface_hub import DatasetCard
# Load card
card = DatasetCard.load("<namespace>/<repo_id>")
# Modify card content
card.content = ...
# Push card to the Hub
card.push_to_hub("<namespace>/<repo_id>")
```

However, the best solution would be to use the features info stored in the header of the Parquet shards generated with `push_to_hub` on the viewer side to avoid unexpected issues such as this one. This shouldn't be too hard to address. Thanks for reporting @FrancescoSaverioZuppichini.

For future issues with your specific dataset, you can use its "Community" tab to start a conversation: https://huggingface.co/datasets/Francesco/cell-towers/discussions/new Thanks @albertvillanova , @mariosasko I was not aware of this requirement from the doc (must have skipped :sweat_smile: )

Confirmed, adding back `dataset_info` fixed the issu
