Feature: Add CI/CD with tests

[JonathanDagan]

Add tests with automatic test runs & deployment to NPM

To make sure we add new features/templates and keep a standard across the board I suggest we create a testing plan of how we'll test the use of the create-mf-app tool automatically. Also to make @jherr life easier we could have the package packaged and released to NPM for each new tag we create on this repo.

We'll need to do the following:

• [ ] Strategize a way to test the create-mf-app tool
• [ ] Implement tests
• [ ] Create a testing pipeline
• [ ] Create a packaging & publish to npm pipeline

I'm seeing what y'all are doing here and I love it. I will get around to handling the PRs, but I'm just super busy with job interviews and content creation. I should be able to get to accepting your PRs tonight or tomorrow though.
