CI failing on main

CI is failing to run as the pinned software environments can no longer be reproduced. It's been a few years since these environments were updated. It also looks like there were some problems updating the solve in #232.

To get CI unblocked again we need to update the pinned dependencies following the [instructions in the README](https://github.com/dask/dask-examples#updating-the-binder-environment) and then make sure CI can build the notebooks, containers, docs, etc.

Inizia con le istruzioni del README su “updating the Binder environment” e esamina i problemi risolti in precedenza nell'issue #232. Aggiorna le dipendenze bloccate, quindi esegui i controlli CI del repository per verificare che notebook, container e documentazione vengano compilati correttamente.
