Modernize Test workflow and Dockerfile images

This commit updates the CI configuration to resolve build failures
and align the test environments with modern, supported versions.

- Replaces deprecated `ubuntu-20.04` runners with `ubuntu-22.04`
  in the GitHub Actions workflow, fixing the hanging jobs.
- Adds QEMU and Docker Buildx to `arm64` jobs to enable cross-platform
  image builds.
- Upgrades the Debian test environment from a Bullseye-based image
  to a Bookworm-based one, and updates Node.js from v18 to v22 (LTS).
- Updates the Python 2.7 test environment to use an `ubuntu:22.04`
  base image and installs Python 2.7 via the `deadsnakes` PPA.
