HuggyLingo Bot: Add language information to your dataset

Hi this is a message from the Hugging Face Model Hub Librarian Bot!

This is a pull request suggesting to add `en` as language metadata for your dataset (defined in the `YAML` block of your dataset's `README.md`).

The suggestion to add `en` to your dataset metadata was generated by downloading the first 20 rows of your dataset and passing likely text based columns from your dataset through a [language detection model](https://huggingface.co/facebook/fasttext-language-identification).
This model return `en` with a confidence of `0.9`. Whilst efforts were made to filter out likely wrong predictions it is possible that this suggestion is not correct.

If you think that this is the case please feel free to close this PR and make sure to let us know in a comment. You will probably still find it helpful to add metadata for language to your dataset. You can do this by [editing your dataset's `README.md` file](https://huggingface.co/datasets/davanstrien/testmodelcardwdata/edit/main/README.md)

This PR was made by Librarian Bot. Feel free to get in touch with [@davanstrien](https://huggingface.co/davanstrien) with feedback or questions.
