Publish a new release of jupyterlab-classic to inform about rename

[krassowski]

To make users who earlier installed jupyterlab-classic aware of the rename it might be a good idea to publish a new release of jupyterlab-classic to PyPI/npm/both which would add a note about the rename in the README and maybe a console.log/logging.warn message to inform existing users about the need to update their environment/requirements files.

I think that NPM allows for installation-time logs about this but it might not be visible when installing from extension manager (which one should not do probably for this extension which requires a backend component).

Possibly a good place to put a notice would be the description field as it shows up in the Extension Manager GUI.

Thanks @krassowski for the suggestion 👍

There is now a 0.1.x branch that points to the commit before the rename to RetroLab: https://github.com/jupyterlab/retrolab/tree/0.1.x

We could do the change in that branch and then publish the packages.

Would you like to open a PR? Thanks!

Just published a 0.1.11 version to PyPI manually: https://pypi.org/project/jupyterlab-classic/0.1.11/

Probably this is enough for jupyterlab-classic. We'll likely do something similar for RetroLab later: #356
