[GEM] add WikiLingua cross-lingual abstractive summarization dataset
Hi @KMFODA ! A version of WikiLingua is actually already accessible in the [GEM dataset](https://huggingface.co/datasets/gem)

You can use it for example to load the French to English translation with:
```python
from datasets import load_dataset
wikilingua = load_dataset("gem", "wiki_lingua_french_fr")
```

## Adding a Dataset
- **Name:** WikiLingua
- **Description:** The dataset includes ~770k article and summary pairs in 18 languages from WikiHow. The gold-standard article-summary alignments across languages were extracted by aligning the images that are used to describe each how-to step in an article.
- **Paper:** https://arxiv.org/pdf/2010.03093.pdf
- **Data:** https://github.com/esdurmus/Wikilingua
- **Motivation:** Included in the GEM shared task. Multilingual.

Instructions to add a new dataset can be found [here](https://huggingface.co/docs/datasets/share_dataset.html).
