push to hub fails with huggingface-hub 0.5.0

## Describe the bug
`ds.push_to_hub` is failing when updating a dataset in the form "org_id/repo_id"

## Steps to reproduce the bug
```python
from datasets import load_dataset
ds = load_dataset("rubrix/news_test")
ds.push_to_hub("<your-user>/news_test", token="<your-token>")
```

## Expected results
The dataset is successfully uploaded

## Actual results
An error validation is raised:

```bash
if repo_id and (name or organization):
>           raise ValueError(
                "Only pass `repo_id` and leave deprecated `name` and "
                "`organization` to be None."
E               ValueError: Only pass `repo_id` and leave deprecated `name` and `organization` to be None.
```

## Environment info
<!-- You can run the command `datasets-cli env` and copy-and-paste its output below. -->
- `datasets` version: 1.18.1
- `huggingface-hub`: 0.5
- Platform: macOS
- Python version: 3.8.12
- PyArrow version: 6.0.0

Hi ! Indeed there was a breaking change in `huggingface_hub` 0.5.0 in `HfApi.create_repo`, which is called here in `datasets` by passing the org name in both the `repo_id` and the `organization` arguments:

https://github.com/huggingface/datasets/blob/2230f7f7d7fbaf102cff356f5a8f3bd1561bea43/src/datasets/arrow_dataset.py#L3363-L3369

I think we should fix that in `huggingface_hub`, will keep you posted. In the meantime please use `huggingface_hub` 0.4.0

I'll be sending a fix for this later today on the `huggingface_hub` side.

The error would be converted to a `FutureWarning` if `datasets` uses kwargs instead of positional, for example here: 

https://github.com/huggingface/datasets/blob/2230f7f7d7fbaf102cff356f5a8f3bd1561bea43/src/datasets/arrow_dataset.py#L3363-L3369

to be:

``` python
            api.create_repo(
                name=dataset_name,
                token=token,
                repo_type="dataset",
                organization=organization,
                private=private,
            )
```

But `name` and `organization` are deprecated in `huggingface_hub=0.5`, and people should pass `repo_id='org/name` instead. Note that `repo_id` was introduced in 0.5 and if `datasets` wants to support older `huggingface_hub` versions (which I encourage it to do), there needs to be a helper function to do that. It can be something like:


```python
def create_repo(
    client,
    name: str,
    token: Optional[str] = None,
    organization: Optional[str] = None,
    private: Optional[bool] = None,
    repo_type: Optional[str] = None,
    exist_ok: Optional[bool] = False,
    space_sdk: Optional[str] = None,
) -> str:
    try:
        return client.create_repo(
            repo_id=f"{organization}/{name}",
            token=token,
            private=private,
            repo_type=repo_type,
            exist_ok=exist_ok,
            space_sdk=space_sdk,
        )
    except TypeError:
        return client.create_repo(
            name=name,
            organization=organization,
            token=token,
            private=private,
            repo_type=repo_type,
            exist_ok=exist_ok,
            space_sdk=space_sdk,
        )
```

in a `utils/_fixes.py` kinda file and and be used internally.

I'll be sending a patch to `huggingface_hub` to convert the error reported in this issue to a `FutureWarning`.

PR with the hotfix on the `huggingface_hub` side: https://github.com/huggingface/huggingface_hub/pull/822

We can definitely change `push_to_hub` to use `repo_id` in `datasets` and require `huggingface_hub>=0.5.0`.

Let me open a PR :)

`huggingface_hub` 0.5.1 just got released with a fix, feel free to update `huggingface_hub` ;)
