Generate Hashicorp Configuration Language (HCL) by default (#31)

### Background and Links
* Generating HCL is better than generating JSON; debugging and switching
to manual writing are easier

### Changes and Testing
* Flip the HCL default
* Allow formatting with `tofu`
* Bump versions

### Questions and Followup
* How to migrate to OpenTofu generally? Support both `terraform` and
`tofu` on the command line for a time? (Does an environment variable or
detection function choose?) Or cut over hard?
* How to adopt `asdf`? (Or is there a better alternative?) Can we get to
a place where GitHub Actions continuously tests the same developer
environment setup steps we expect people to run on their local
development machines?
