jsonlines files don't load with `load_dataset`
Hi @serenalotreck,

We use Apache Arrow `pyarrow` to read jsonlines and it throws an error when trying to load your data files:
```python
In [1]: import pyarrow as pa

In [2]: data = pa.json.read_json("train.jsonl")
---------------------------------------------------------------------------
ArrowInvalid                              Traceback (most recent call last)
<ipython-input-14-e9b104832528> in <module>
----> 1 data = pa.json.read_json("train.jsonl")

.../huggingface/datasets/venv/lib/python3.9/site-packages/pyarrow/_json.pyx in pyarrow._json.read_json()

.../huggingface/datasets/venv/lib/python3.9/site-packages/pyarrow/error.pxi in pyarrow.lib.pyarrow_internal_check_status()

.../huggingface/datasets/venv/lib/python3.9/site-packages/pyarrow/error.pxi in pyarrow.lib.check_status()

ArrowInvalid: JSON parse error: Column(/ner/[]/[]/[]) changed from number to string in row 0
```

I think it has to do with the data structure of the fields "ner" (and also "relations"):
```json
"ner": [
  [
    [0, 4, "Biochemical_process"], 
    [15, 16, "Protein"]
  ], 
```
Arrow interprets this data structure as an array, an arrays contain just a single data type: 
- when reading sequentially, it finds first the `0` and infers that the data is of type `number`;
- when it finds the string `"Biochemical_process"`, it cannot cast it to number and throws the `ArrowInvalid` error

One solution could be to change the data structure of your data files. Any other ideas, @huggingface/datasets ? Hi @albertvillanova, 

Thanks for the explanation! To the best of my knowledge, arrays in a json [can contain multiple data types](https://docs.actian.com/ingres/11.2/index.html#page/SQLRef/Data_Types.htm), and I'm able to read these files with the `jsonlines` package. Is the requirement for arrays to only have one data type specific to PyArrow?

I'd prefer to keep the data structure as is, since it's a specific input requirement for the models this data was generated for. Any thoughts on how to enable the use of `load_dataset` with this dataset would be great! Hi again @serenalotreck,

Yes, it is specific to PyArrow: as far as I know, Arrow does not support arrays with multiple data types.

As this is related specifically to your dataset structure (and not the `datasets` library), I have created a dedicated issue in your dataset page: https://huggingface.co/datasets/slotreck/pickle/discussions/1

Let's continue the discussion there! :hugs:   > Hi again @serenalotreck,

This is really terrible. My JSONL format data is very simple, but I still report this error
![image](https://github.com/huggingface/datasets/assets/58240629/e3fed922-ced4-406c-b5bc-90a4b891c4ee)
The error message is as follows：
  File "pyarrow/_json.pyx", line 290, in pyarrow._json.read_json
  File "pyarrow/error.pxi", line 144, in pyarrow.lib.pyarrow_internal_check_status
  File "pyarrow/error.pxi", line 100, in pyarrow.lib.check_status
pyarrow.lib.ArrowInvalid: JSON parse error: Column(/inputs) changed from string to number in row 208

### Describe the bug

While [the docs](https://huggingface.co/docs/datasets/upload_dataset#upload-dataset) seem to state that `.jsonl` is a supported extension for `datasets`, loading the dataset results in a `JSONDecodeError`.

### Steps to reproduce the bug

Code:
```
from datasets import load_dataset
dset = load_dataset('slotreck/pickle')
```

Traceback:
```

### Expected behavior

For the dataset to be loaded without error.
