Fix `/api/repos/move` documentation in api.md (#1095)
* Fix `/api/repos/move` documentation in api.md
Related to https://github.com/huggingface/huggingface_hub/issues/1813.
In `/api/repos/move`, we (I? :smile:) forgot to mention the `type` parameter to specify the repo type.
cc @enzostvs you would have to update the API Playground as well to add this parameter. Thanks in advance!
* patch
