Retiring Project that Provided Similar Functionality

[jovanni-hernandez]

Description

A few years ago I developed a plugin for Jupyter, JupyterLab Scheduler, that provided functionality for scheduling the execution of notebooks. Over the years, I've kept the plugin up to date, with the assistance of a few other open source contributors who also found the plugin useful. While performing some recent updates, one of our users discovered that an official scheduler had been released and brought it my attention, so I'd like to retire my project and start pointing users who stumble on my project to the official repo. @dlqqq indicated that I should open a new issue to formalize this transition.
