macOS Ensure ZSH Default Shell

Ensures ZSH is configured to be used as the default command-line shell

Overview

This script ensures ZSH is used as the default shell by ensuring it is added to /etc/shells. The script also ensures ZSH is available at /usr/local/bin/zsh on ARM64 systems by symlinking the Homebrew ZSH shell to /usr/local/bin/zsh if it is missing.
