Binder does not work with Jupyter Server v2

[fcollonval]

Description

If you install jupyter-server v2 as a dependency on Binder, binder will not work.

Reproduce

You could reproduce the error locally by

1. installing jupyter-server v2, jupyterlab and notebook
2. start JupyterLab with: jupyter notebook --NotebookApp.default_url="/lab"
3. You are stuck on the login page

I try setting password and token to blank or to something. But it does not work. There is something about the cookie that gets cleaned I guess.

Expected behavior

You can access the server.
