Error when doing `push_to_hub` two times in a row

When doing tokenizer.push_to_hub() with the same tokenizer that was already uploaded (can happen in a notebook in particular), we have a git error:

Please open a new issue when you encounter a bug that is different. Here the problem is that you are not passing a valid name, it should just be model.push_to_hub("my-model-name") (happy to discuss more on another issue if you still have problems).
