Update README.md

I used the `huggingface_hub` API to open the PR rather than doing it manually.
It automatically changed the license (it is not deleted, it is just changed to be placed after the language tag).
It is also the one who changed the author's name. The fact that it changed the accents should be reported to the HF team so that the encoding is done in utf-8. I changed the accent manually.
Everything should be fine now.
