add Bengali Hate Speech dataset
@lhoestq I think you might want to look at the dataset, and the first data instances mentioned in the README.md is very much offensive. Though this dataset is based on hate speech but I found the dataset heavily disturbing as Bengali is my native language. Hi @tanmoyio indeed you're right.
We should *at least* add very explicit mentions in the dataset card that the content of this dataset contains very offensive language. We should also put it in perspective with the tasks it tries to solve, the annotation process and the limitations.

We have to make sure that nothing is unclear/misleading nor could lead to bad usage of the dataset.

What do you think @tanmoyio ?
Also feel free to suggest modifications in the dataset cards if you feel like some sections require corrections or more details > Hi @tanmoyio indeed you're right.

yeah I agree with you. It would be good if "Personal and Sensitive Information" and "Considerations for Using the Data" is being explained properly in the README.md. @stevhliu  please let me know if there is anything else you'd like to see! This looks ok to merge for me. Let me know @stevhliu and @tanmoyio if you want to add something or if it looks good to you looks good to me @lhoestq 👍  merging since the CI is fixed on master
