threejs-sage: make it available as a jupyter nbextension
https://github.com/void-linux/void-packages/pull/36644

Description:
Adds a symlink in /usr/share/jupyter/nbextensions, so that the js is available in a jupyter notebook.

Otherwise, using 3d plots in the jupyter notebook will hit jsdelivr.net.
