jupyter labextension install error

[tmtabor]

This extension no longer installs in JupyterLab 3.x. It throws an error when trying to run jupyter labextension install cy-jupyterlab, stating that css-loader 7 is not compatible with Node 16.

I suspect that one of this extension's dependencies has been recently updated and now requires css-loader 7, which itself requires node 18 or higher. And since JupyterLab 3.x always uses Node 16 to build, this results in the aforementioned error.

Solving this issue is likely a matter of updating package.json to be more specific regarding the versions of this extension's dependencies.
