feat(aws-tools)!: Update AWS CLI to v2

Install the latest version of the AWS CLI (v2) using an AWS maintained mechanism.

It looks like installing the AWS CLI isn't maintained by AWS as:
- It installs v1
- It is not listed on https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html

Install the AWS CLI via an AWS provided zip file.
