Description

• Cartesian: move parsing base python version

Requirements

• All fixes and/or new features come with corresponding tests.
• Important design decisions have been documented in the appropriate ADR inside the docs/development/ADRs/ folder.

I still see references to 3.10 in

• pyproject.toml: the section [tool.ruff] has a target-version
• .devcontainer/Dockerfile
• ci/Dockerfile
• the jupyter notebooks under docs/user/next/workshop (not sure if all of those need to change)

Those I believe are "last run version", so irrelevant.

This is passing checks now. I turned on 3.11 in the stead of 3.10 in the ci

Looks good to me now.

lgtm, but we need to update our deployment environment first, therefore I need to block this PR for a bit.

All good, merge when ready.
