Show gem versions in CI failure output instead of matrix params

Previously displayed:
  dummy-app-integration-tests (3.2, 20, minimum)

Now displays:
  dummy-app-integration-tests (3.2, 20, minimum) (Ruby 3.2, Node 20, Shakapacker 8.2.0, React 18)

This makes it immediately clear which gem versions are being tested,
making it easier to understand test failures and replicate them locally.
