JupyterLab Widgets Extension

`jupyterlab-widgets` is the JupyterLab frontend extension that provides the necessary framework for rendering interactive `ipywidgets` within JupyterLab notebooks and interfaces. It enables the rich interactive experiences defined by the core `ipywidgets` Python library. As of version 3.0.16, this extension is compatible with JupyterLab 3 and 4, and for many modern setups, it is automatically handled or included when `ipywidgets` is installed.
