fix: Install molecule-podman driver for CI/CD tests

The test stage was failing because molecule couldn't find the podman
driver. The issue was that 'molecule[podman]' extra doesn't exist in
molecule 25.12.0. Install 'molecule-podman' package instead which
provides the required podman driver for molecule.
