fork: Test suite

[bazaah]

Need to figure out some method for testing changes.

Ideally, we have some unit tests that can run locally and then figure out how we're going to handle the integration testing in CI

[bazaah]

So my idea here is to settle a set of tooling that is relatively easy to support locally as well as in CI.

For now, we'll need at least:

• [ ] terradoc
• [ ] tflint
• [ ] terraform (for formatting) (NB: look into opentofu)
• [ ] changelog manager (git-cliff?)

I'm not sure how to add back integration testing yet (how expensive is a github org?)
