Thanks, I updated the file.
A small suggestion can you mention this link https://github.com/huggingface/datasets/tree/main/src/datasets/utils/resources/ in the contribution page. So that others will know the acceptable values for the tags.

Thank you. In our docs Create a dataset card, we suggest using the Datasets Tagging application: https://huggingface.co/spaces/huggingface/datasets-tagging
