Packet: Broken AWS provider due to version mismatch

[johananl]

When deploying a Packet cluster by following the docs, terraform init is currently failing with the following error:

Initializing provider plugins...
- Checking for available provider plugins on https://releases.hashicorp.com...

- Downloading plugin for provider "tls" (1.2.0)...
- Downloading plugin for provider "packet" (1.7.2)...

No provider "aws" plugins meet the constraint "~> 1.57,~> 2.8.0".

The version constraint is derived from the "version" argument within the
provider "aws" block in configuration. Child modules may also apply
provider version constraints. To view the provider versions requested by each
module in the current configuration, run "terraform providers".

To proceed, the version constraints for this provider must be relaxed by
either adjusting or removing the "version" argument in the provider blocks
throughout the configuration.

This is caused by the following conflicting provider versions:
