Loading a dataset from the hub fails if you happen to have a folder of the same name

### Describe the bug

I'm not 100% sure this should be considered a bug, but it was certainly annoying to figure out the cause of. And perhaps I am just missing a specific argument needed to avoid this conflict. Basically I had a situation where multiple workers were downloading different parts of the glue dataset and then training on them. Additionally, they were writing their checkpoints to a folder called `glue`. This meant that once one worker had created the `glue` folder to write checkpoints to, the next worker to try to load a glue dataset would fail as shown in the minimal repro below. I'm not sure what the solution would be since I'm not super familiar with the `datasets` code, but I would expect `load_dataset` to not crash just because i have a local folder with the same name as a dataset from the hub.

### Steps to reproduce the bug

```
In [1]: import datasets

In [2]: rte = datasets.load_dataset('glue', 'rte')

### Expected behavior

Dataset is still able to be loaded from the hub even if I have a local folder with the same name.

### Environment info

datasets version: 2.6.1
