## Describe the bug
codeparrot/github-code fails to load with a `TypeError: get_patterns_in_dataset_repository() missing 1 required positional argument: 'base_path'`

## Steps to reproduce the bug
```python
from datasets import load_dataset
```

## Expected results
loaded dataset object

## Actual results
```python
 [3]: dataset = load_dataset("codeparrot/github-code")

Comments:
I believe the issue is in `codeparrot/github-code`. `base_path` param is missing - https://huggingface.co/datasets/codeparrot/github-code/blob/main/github-code.py#L169

Function definition has changed.
https://github.com/huggingface/datasets/blob/0e1c629cfb9f9ba124537ba294a0ec451584da5f/src/datasets/data_files.py#L547

@mariosasko could you please confirm my finding? And are there any changes that need to be done from my side?

Good catch ! We recently did a breaking change in `get_patterns_in_dataset_repository`, I think we can revert it

> Good catch ! We recently did a breaking change in `get_patterns_in_dataset_repository`, I think we can revert it

I can't wait for that releasee. Broke my application

This simple workaround should fix: https://huggingface.co/datasets/codeparrot/github-code/discussions/2

`get_patterns_in_dataset_repository` can treat whether `base_path=None`, so we just need to make sure that codeparrot/github-code `_split_generators` calls with such an argument.

I am afraid your suggested change @gugarosa will break compatibility with older datasets versions that don't have `base_path` argument in `get_patterns_in_dataset_repository`, as a workaround while the issue gets resolved in `datasets` can you downgrade your datasets version  to `<=2.1.0` ? 
@lvwerra do you think we should adapt the script to check the datasets version before calling `get_patterns_in_dataset_repository`?

Actually I think it's just simpler to fix it in the dataset itself, let me open a PR

EDIT: PR opened here: https://huggingface.co/datasets/codeparrot/github-code/discussions/3

PR is merged, it's working now ! Closing this one :)

You are definitely right, sorry about it. I always keep forgetting that we need to keep in mind users from past versions, my bad.
