Update CHANGES to reiterate Terraform Module Registry deprecation 

* Terraform supports sourcing modules from either Git repos or from
their own hosted Terraform Module Registry, introduced a few years ago
* Typhoon docs have always shown using Git-based module sources, not
the Terraform Module Registry. For example, module usage should be
`source = "git::https://github.com/poseidon/typhoon/...` not
`source = poseidon/kubernetes/...`
* Typhoon published Flatcar Linux modules (CoreOS Container Linux at the time)
to Terraform Module Registry, but the approach has a number of drawbacks
for publishers and for users.
  * Terraform's Module Registry requires subtree mirroring Typhoon to special
  terraform-platform-kubernetes repos. This distorts Git history,
  requires special automation, and the registry's naming requirements
  don't allow us to publish our full matrix of modules (Fedora CoreOS
  and Flatcar Linux, across AWS, Azure, GCP, on-prem, and DigitalOcean)
  * Terraform's Module Registry only supports release versions (no commit SHAs
  or forks)
* Ultimately, the Terraform Module Registry limits user flexibility, has
tedious publishing constraints, and introduces centralization where the
current decentralized Git-based approach is simpler and more featureful

Note: This does not affect Terraform _Providers_ like `poseidon/matchbox`
or `poseidon/ct`. For Terraform providers, Terraform's centralized
platform eases provider plugin installation and provides value
