Update security scan scripts to improve error handling and output redirection

- Modified run_checkov.sh and run_snyk.sh to redirect error output to /dev/null while ensuring failure messages are logged for transparency.
- Enhanced report generation processes to create minimal output in case of failures, improving user experience by reducing clutter in logs.
