Outdated Link for mkqa Dataset
State: closed
Labels: name: bug

## Describe the bug
The URL used to download the mkqa dataset is outdated. It seems the URL to download the dataset is currently https://github.com/apple/ml-mkqa/blob/main/dataset/mkqa.jsonl.gz instead of https://github.com/apple/ml-mkqa/raw/master/dataset/mkqa.jsonl.gz (master branch has been renamed to main).

## Steps to reproduce the bug
```python
from datasets import load_dataset

dataset = load_dataset("mkqa")
```

## Expected results
downloads the dataset

## Actual results
```python
