Alerts Not Triggering for Failed DQ Test Cases After Upgrade to 1.5.4

[Siddhanttimeline]

Description:
SMTP alerting for failed DQ (Data Quality) test cases on table followers has stopped working. The system seems to be detecting events correctly, but no alert emails are being sent.

Steps to Reproduce:

1. Upgrade OpenMetadata from version 1.4.3 to 1.5.4.
2. Set up SMTP email alerts for failed DQ test cases.
3. Run tests that generate DQ test failures.
4. Monitor if alert emails are sent to the configured followers.

Expected Behavior:
Email alerts should be triggered and sent to the followers when a DQ test case fails.

Observed Behavior:

1. Subscriptions are correctly detecting change events.
2. Alert triggers are being evaluated properly.
3. Quartz alert jobs are being created as expected.
4. However, no alert emails are being sent for failed DQ test cases.

Environment:

1. OpenMetadata Version: 1.5.4
2. Previous Version: 1.4.3 (where the issue was not present)
3. SMTP setup is confirmed to be working and has not changed since the upgrade.
