### Feature request

Currently, when datasets are created, they can be versioned by passing the `version` argument to `load_dataset(...)`. For example creating `outcomes.csv` on the command line

```
echo "id,value\n1,0\n2,0\n3,1\n4,1\n" > outcomes.csv
```
and creating it
```
import datasets
dataset = datasets.load_dataset(
    "csv",
    data_files ="outcomes.csv",
    keep_in_memory = True,
    version = '1.0.0')
```

The version info is stored in the `info` and can be accessed e.g. by `next(iter(dataset.values())).info.version`

This dataset can be uploaded to the hub with `dataset.push_to_hub(repo_id = "maomlab/example_dataset")`. This will create a dataset  on the hub with the following in the `README.md`, but it doesn't upload the version information:

```
---
dataset_info:
  features:
  - name: id
    dtype: int64
  - name: value
    dtype: int64
  splits:
  - name: train
    num_bytes: 64
    num_examples: 4
  download_size: 1332
  dataset_size: 64
configs:
- config_name: default
  data_files:
  - split: train
    path: data/train-*
---
```

However, when I download from the hub, the version information is missing:

```
dataset_from_hub_no_version = datasets.load_dataset("maomlab/example_dataset")
next(iter(dataset.values())).info.version
```

I can add the version information manually to the hub, by appending it to the end of config section:

```
...
configs:
- config_name: default
  data_files:
  - split: train
    path: data/train-*
  version: 1.0.0
---
```

And then when I download it, the version information is correct.





### Motivation

### Why adding version information for each config makes sense
  1. The version information is already recorded in the dataset config info data structure and is able to parse it correctly, so it makes sense to sync it with `push_to_hub`. 
  2. Keeping the version info in at the config level is different from version info at the branch level. As the former relates to the version of the specific dataset the config refers to rather than the version of the dataset curation itself.

## A explanation for the current behavior:
In [datasets/src/datasets/info.py:159](https://github.com/huggingface/datasets/blob/fb91fd3c9ea91a818681a777faf8d0c46f14c680/src/datasets/info.py#L159C1-L160C1
), the `_INCLUDED_INFO_IN_YAML` variable doesn't include `"version"`.

If my reading of the code is right, adding `"version"` to `_INCLUDED_INFO_IN_YAML`, would allow the version information to be uploaded to the hub.

### Your contribution

Request: add `"version"` to `_INCLUDE_INFO_IN_YAML` in [datasets/src/datasets/info.py:159](https://github.com/huggingface/datasets/blob/fb91fd3c9ea91a818681a777faf8d0c46f14c680/src/datasets/info.py#L159C1-L160C1
)
