Since Poetry v2 release, I updated Poetry containers to be built with Poetry v2. If this is causing an issue, we could fix poetry installation to latest v1 version with: pip install "poetry>=1.8,<2.0". Migrate to Poetry v2 (clients/python/silkaj#499) (docker/python3/poetry!11 - merged)

Todos

• Update pyproject.toml to latest format
  • support include field.
  • Keep classifiers and dependencies dynamic
• duniterpy#215 (closed)
• docker/python3/poetry!11 (merged): python:3.13-alpine image is using Poetry v1 from Alpine repository
