Pull request overview

This PR migrates the GitHub Actions CI workflow from using the actions/setup-python action to using Docker containers with Python images. This approach runs the entire job inside a Python container rather than installing Python on the GitHub Actions runner.

Key changes:

• Replaced actions/setup-python@v5 with container-based Python images (python:{version}-trixie)
• Updated Python version format from "3.10.x" to "3.10" to match Docker tag conventions
• Applied the container approach to both test and publish-release jobs

• The snok/install-poetry action may not work correctly when running inside a container. This action is designed to run on the GitHub Actions runner host, not inside a Docker container. When using containers, it's typically better to install Poetry directly using pip in a separate step, like:

- name: Install Poetry
  run: python -m pip install -U pip poetry

This approach is already being used in the publish-release job (line 56) and would be more consistent across both jobs.

      - name: Install Poetry
        uses: snok/install-poetry@v1
        with:
          virtualenvs-in-project: true

not sure there's a big argument for making all projects test like this.. it's more useful in the case of RP components which we use as containers elsewhere
