fix: Correct CI/CD deployment script variable expansion

Fixed the deployment script to properly expand variables in the SSH
session by removing single quotes from the heredoc delimiter. Also
added error handling with 'set -e' and removed dependency on
/opt/silverlabs/website directory that doesn't exist.
