> Why is there a comma after ]

It's ok to have a comma after the last entry in a dict, as line 72 below.

The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/transformers/pr_34957). All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update.
