EmptyDatasetError: The directory at /metadata.jsonl doesn't contain any data files

### Describe the bug

while trying to load custom dataset from jsonl file, I get the error: "metadata.jsonl doesn't contain any data files"

### Steps to reproduce the bug

This is my [metadata_v2.jsonl](https://github.com/user-attachments/files/16016011/metadata_v2.json) file.  I have this file in the folder with all images mentioned in that json(l) file.

Through below mentioned command I am trying to load_dataset so that I can upload it as mentioned here on the [official website](https://huggingface.co/docs/datasets/en/image_dataset#upload-dataset-to-the-hub).

````
from datasets import load_dataset

dataset = load_dataset("imagefolder", data_dir="path/to/jsonl/metadata.jsonl")
````

error:

````

EmptyDatasetError: The directory at path/to/jsonl/file/metadata.jsonl doesn't contain any data files`
```

### Expected behavior

It should be able load the whole file in a format of "dataset" inside the dataset variable. But it gives error "The directory at "path/to/jsonl/metadata.jsonl" doesn't contain any data files."

### Environment info

I am using conda environment.

Comments:
Hi ! `data_dir=` is for directories, can you try using `data_files=` instead ?

If you are trying to load your image dataset from a local folder, you should replace "data_dir=path/to/jsonl/metadata.jsonl" with the real folder path in your computer.

Ah yes. My bad. I was giving file name. I should have given the folder directory as the path. That solved my issue. Thank you @albertvillanova and @lhoestq.
