JuptyterLab App settings

The JupyterLab app has the ability to post alerts, for example to notify the user that an update is available.

Suppress alerts by setting the following in .jupyter/lab/user-settings/@jupyterlab/apputils-extension/notification.jupyterlab-settings:

{
    "checkForUpdates": false,
    "doNotDisturbMode": false,
    "fetchNews": "none"
}
