One or several metadata.jsonl were found, but not in the same directory or in a parent directory
State: open | Author: blghtr (NONE)

### Describe the bug

An attempt to generate a dataset from a zip archive using imagefolder and metadata.jsonl does not lead to the expected result. Tried all possible locations of the json file: the file in the archive is ignored (generated dataset contains only images), the file next to the archive like [here](https://huggingface.co/docs/datasets/image_dataset#imagefolder) leads to an error:
```

```

### Steps to reproduce the bug

1. Organize directory structure like in the docs:
folder/metadata.jsonl
folder/train.zip

2. Run load_dataset("imagefolder", data_dir='folder/metadata.jsonl', split='train')

### Expected behavior

Dataset generated with all additional features from metadata.jsonl

### Environment info

- `datasets` version: 2.11.0
- Platform: Windows-10-10.0.22621-SP0
- Python version: 3.9.0
- Huggingface_hub version: 0.13.4
- PyArrow version: 11.0.0
- Pandas version: 1.5.3


Comments: Also, when generated from a zip archive, the dataset contains only a few images. In my case, 20 versus 2000+ contained in the archive. The generation from folders works as expected.

Thanks for reporting, @blghtr.

You should include the `metadata.jsonl` in your ZIP archives, at the root level directory.

I agree that our documentation is not clear enough. Maybe we could improve it.

You can find a dummy dataset example here: https://huggingface.co/datasets/albertvillanova/tmp-imagefolder-metadata

```
tmp-imagefolder-metadata/
└── data/
    ├── train.zip
    └── valid.zip
```
where, the directory structure within the `train.zip` archive is:
```
metadata.jsonl
train/
    ├── bharatanatyam/
        └── bharatanatyam_original_113.jpg_70c297a2-e2f2-4ed8-b93c-0c03d0809fe2.jpg
    └── kathak/
        └── kathak_original_10.jpg_2c4a2c3d-47fc-4b33-9c09-38b542826632.jpg
```
and the metadata file contains:
```
{"file_name": "train/bharatanatyam/bharatanatyam_original_113.jpg_70c297a2-e2f2-4ed8-b93c-0c03d0809fe2.jpg", "text": "first"}
{"file_name": "train/kathak/kathak_original_10.jpg_2c4a2c3d-47fc-4b33-9c09-38b542826632.jpg", "text": "second"}
```
