Jupyter lab 4 (on sepal jellyfish) breaks ipyleaflet traits

[dfguerrerom]

As it was reported initially on: jupyterlab/jupyterlab#14829, some ipyleaflet traits are broken with jupyter lab 4... this will cause some of the tools developed with this python package to experience unexpected behaviors, such as not updating bounds or modifying the map zoom levels.
I post it here just to keep track of the development of one solution.

while this is worked on from ipyleaflet side, do you think it would be possible to pin the Jupyterlab version here:

sepal/modules/sandbox/script/init_jupyter.sh

Line 18 in e2f0d5b

/usr/bin/python3 -m pip install jupyterlab

This is something we have considered, but we have first to test if Jupyterlab<4 works well with ipywidgets, voila, and ipyvuetify

Until ipyleaflet for jupyterlab 4 is updated, we'll use @cdanielw fork: https://github.com/cdanielw/ipyleaflet with the fix.
