Running mypy via precommit with --install-type --non-interactive seem to silence some errors

Commencez par .pre-commit-config.yaml et reproduisez les deux commandes pre-commit mypy indiquées dans l’issue. Comparez le comportement avec et sans --non-interactive, puis vérifiez les erreurs signalées dans ipykernel/pylab/config.py, ipykernel/pylab/backend_inline.py et ipykernel/ipkernel.py. La tâche est terminée lorsque la cause des diagnostics différents est établie et que le comportement prévu de la configuration est documenté ou corrigé.

It seem to be just --install-types

I also get way more errors running mypy manually, but I think this is because of missing dependencies.
