Poetry 2.3.0 dropped Python 3.9 support. Without cache the installer fetches the latest version (currently 2.3.2), which fails on the python:3.9-slim-bookworm base image. Pin to 2.2.1, the last release compatible with Python 3.9.

Title: fix(docker): pin Poetry to 2.2.1 for Python 3.9 compatibility
Base:
main(apache/incubator-devlake)Summary
The
backend/Dockerfileinstalls Poetry without pinning a version:RUN curl -sSL https://install.python-poetry.org | python3 -Poetry 2.3.0 dropped support for Python 3.9. Since the base image uses
python:3.9-slim-bookworm, the unpinned installer now fetches an incompatible version (currently 2.3.2), causing the build to fail when there is no Docker layer cache available.Reference: https://python-poetry.org/blog/announcing-poetry-2.3.0/
Current CI builds succeed only because the cached
devlake:baseimage still contains a Poetry layer from a previous compatible version. Any cache invalidation (base image security update, forced rebuild, new registry) will break the build with:This PR pins Poetry to 2.2.1, the last release compatible with Python 3.9.
Does this close any open issues?
Closes #8734

Other Information
An alternative approach would be to upgrade the base image to Python 3.10+ to support Poetry 2.3+, but that has a larger blast radius.
