DataFilesNotFoundError for datasets in the open-llm-leaderboard

### Describe the bug

When trying to get config names or load any dataset within the open-llm-leaderboard ecosystem (`open-llm-leaderboard/details_`) I receive the DataFilesNotFoundError. For the last month or so I've been loading datasets from the leaderboard almost everyday; yesterday was the first time I started seeing this.

### Steps to reproduce the bug

This snippet has three cells:
1. Loads the modules
2. Tries to get config names
3. Tries to load the dataset

I've chosen "davidkim205"'s Rhea-72b-v0.5 model because it is one of the best performers on the leaderboard should likely have no dataset issues:

```python
In [1]: from datasets import load_dataset, get_dataset_config_names

In [2]: get_dataset_config_names("open-llm-leaderboard/details_davidkim205__Rhea
   ...: -72b-v0.5")
