This PR adds a test script that uses the Node.js test runner to run the build script from build-output.js. For now, this only tests that the script completes without errors - it doesn't make any assertions about the different contents of the build directory. The new test script is added to the design tokens package.json file, and a GitHub Actions workflow is added that runs the test script when a PR updates files within the ./packages/design-tokens directory.
The goal of this is to allow us to more safely update the design tokens package and to give us a test framework that we can add new assertions to over time (correctness of select tokens, presence of the expected output formats, etc).
