Add system package verification to goss tests

Verify that apt packages from the OS-specific package list are
installed, matching the pattern used in images-connect and
images-workbench. Uses goss readFile to read the package list
at test time and assert each package is installed.

Rename package list files from ubuntu2204/ubuntu2404 convention
to ubuntu-22.04/ubuntu-24.04 for consistency with other image
repos. Update all Containerfile references.

Closes #37
