Enable integration tests in GitHub Actions

Uncomment the integration test steps in the test workflow to run
./test/integration-test.sh as part of PR checks. This includes:

- Setting up Ko for building Docker images (task build-image)
- Running integration tests via task test-integration
- Docker is already available on ubuntu-latest runners by default

Resolves #4
