Delete noop assignment

This doesn’t seem to do anything: `server_app.contents_manager = DeepnoteContentsManager(parent=server_app)`. What does seem to work is adding this field to a config file, and pointing `jupyterlab` at this config: `"contents_manager_class": "jupyterlab_deepnote.contents.DeepnoteContentsManager"`
