Issue 455 variable viewer fix

[ScottDelbecq]

This PR resolves #455 by adding the --ALL-- tag for the first filter of the variable viewer. This way, by default, the variable viewer will render all the variable of the system.

Also, due to incompatibility between ipywidgets and jupyterlab versions in the .lock file (for some OS such as OSX), the minimal versions have been updated in the pyproject.toml and thus the .lock.
