feat!: (IAC-1474) Update binaries & Terraform providers/modules

[jarpat]

Breaking Notes:

This is a breaking change and will be noted as so in the release notes.
To resolve security warnings we needed to bump up the version of the providers which in turn required us to bump up the minimum required terraform versions.

This transition to this new version should be smooth. Users who run this project directly on their host will need to update the terraform binary and update the providers and modules. Users of the Docker container can build and use the latest release. Users will not be able to manage their infrastructure using an older version of this project once they migrate to this version or initially start with it. More details to come in official release notes.
