Cannot install development environment on Python 3.12

Inizia esaminando le informazioni sulle dipendenze in poetry.lock e riproducendo il problema con poetry install o con il comando pip wheel mostrato nel report. Il lavoro è completato quando l’ambiente di sviluppo si installa correttamente su Python 3.12 con una versione compatibile di PyYAML e un file di lock aggiornato.

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)
