Doing NLP on NLP papers to do NLP ♻️ I had to add it~

I saw that the README template changed while I was working on this 😅 Some TOC titles may be different but I filled it to the best of my knowledge & readme quality check passes now.
ready for review @lhoestq

Thanks ! Good job with the dataset card, the TOC/sections are all good

I have two final comments and then we can merge :)
