Update alert test scripts to include ALERT_DEDUPLICATION_ENABLED variable

- Added the ALERT_DEDUPLICATION_ENABLED environment variable to both test_sendAlert_additional.sh and test_sendAlert_third.sh for better configuration management.
- Refactored assertions in the teardown functions to use a more concise syntax for checking non-empty values.
- Improved HTML and JSON formatting checks to enhance test reliability and clarity.
