Cannot install development environment on Python 3.12

Commencez par examiner les informations sur les dépendances dans poetry.lock et reproduisez l’échec avec poetry install ou la commande pip wheel indiquée dans le rapport. C’est terminé lorsque l’environnement de développement s’installe correctement sur Python 3.12 avec une version compatible de PyYAML et un fichier de verrouillage mis à jour.

Note: This error originates from the build backend, and is likely not a problem with poetry but with pyyaml (6.0) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "pyyaml (==6.0)"'.

I suppose the problem is related to the fact that poetry.lock requires pyyaml == 6.0, but looks like there is a problem to build pyyaml < 6.0.1 for python 3.11 and newer (https://github.com/yaml/pyyaml/issues/736).

Proposed solution

1. Maybe bump pyyaml dependency to the latest 6.0.2?
2. Update poetry.lock for python 3.12 and newer (for pyyaml package wheels are listed for 3.11 and older)
