Updates the included CircleCI config file example.

* Now uses 2.1 style config
* Uses Node Orb
* Use pre-defined node/test job
* Uses Matrix jobs to test multiple node versions.

 ### `.circleci/config.yml` configuration for multiple Node jobs
 
-This example is a minimal configuration for **semantic-release** with a build running Node 6 and 8. See [CircleCI documentation](https://circleci.com/docs/2.0) for additional configuration options.
+This example is a minimal configuration for **semantic-release** with tests running against Node 16 and 14. See [CircleCI documentation](https://circleci.com/docs/2.0) for additional configuration options.
 
-This example create the workflows `test_node_4`, `test_node_6`, `test_node_8` and `release`. The release workflows will [run `semantic-release` only after the all the `test_node_*` are successful](../usage/ci-configuration.md#run-semantic-release-only-after-all-tests-succeeded).
+In this example, the [`circleci/node`](https://circleci.com/developer/orbs/orb/circleci/node) orb is imported (Which makes some node operations easier), then a `release` job is defined which will run `semantic-release`.
+
+To run our `release` job, we have created a workflow named `test_and_release` which will run two jobs, `node/test`, which comes from the node orb and will test our application, and our release job. Here, we are actually making use of [matrix jobs](https://circleci.com/blog/circleci-matrix-jobs/) so that our single `node/test` job will actually be executed twice, once for Node version 16, and once for version 14. Finally, we call our release job with a `requires` parameter so that `release` will only run after `node/test` has successfully tested against v14 and v16.
