Suppress JupyterLab notifications

JupyterLab displays "Would you like to get notified about official Jupyter
news?" banner or "A newer version is available" notification because
JupyterLab default configuration enables news notifications and version
checks
- Add source/overrides.json to disable fetchNews and checkForUpdates
- Update Dockerfile to copy overrides.json to JupyterLab user-settings
