Create .env file in docker-unit-tests directory for proper sourcing

- Add a step to create a .env file in $HOME/tooling/docker-unit-tests after cloning, ensuring the script finds required variables.
- The .env file includes default values and securely injects GH_AUTH_TOKEN from GitHub Secrets.
- This resolves the "filename argument required" error during sourcing.
