## Describe the bug
I get `ConnectionError` when I am trying to load the SciELO dataset. 


When I try the URL with `requests` I get:
```
>>> requests.head("https://ndownloader.figstatic.com/files/14019287")
<Response [302]>
```
And as far as I understand redirections in `datasets` are not supported for downloads. 
https://github.com/huggingface/datasets/blob/807341d0db0728073ab605c812c67f927d148f38/datasets/scielo/scielo.py#L45 



## Steps to reproduce the bug
```python
from datasets import load_dataset

dataset = load_dataset("scielo", "en-es")
```

## Expected results
Download SciELO dataset and load Dataset object


## Actual results

```
