Jupyter Metapackage

The `jupyter` package is a metapackage designed for user convenience, providing a single command to install core Project Jupyter components like Jupyter Notebook, JupyterLab, and the IPython Kernel. It is an empty package that simply declares dependencies on other Jupyter projects, rather than providing direct functionality itself. The current version is 1.1.1, released on August 30, 2024. While the metapackage version updates infrequently, installing it typically pulls in the latest stable versions of its constituent components.
