Update Zathras installer

[grdumas]

The merges in this pull request 1) installs the Ansible AWS collection and 2) freezes the terraform package to version 1.9.8-1.

Description

This PR fixes #131 by adding the ansible-galaxy installation of amazon.aws to the installation process.

Per reviewer request, error handling has been added to the script via set -eu and the use of exit conditions.
