## Describe the bug
Loading QED was fine until 1.15.0.

Not sure where the root cause is, but here are some candidates:
- #3158
- #3120
- #3196
- #2891

## Steps to reproduce the bug
```python
load_dataset("qed")
```

## Expected results
Loading completed.

## Actual results

Scratch that, probably the old and incompatible usage of dataset builder from promptsource.

Actually, re-opening this issue cause the error persists
