Added Run Suspicious_Verdict Responder notification

[EnzoCyberSec]

Summary

Adds a TheHive notification that automatically runs the Suspicious_Verdict Responder (submitted in TheHive-Project/Cortex-Analyzers, see PR #1503) whenever a suspicious:verdict= tag is added to a Case or an Alert. This automates the synchronization between TheHive triage and Suspicious, Thales CERT's case management platform.

What's included

• integrations/vendors/Suspicious/thehive/notifications/run_suspicious_verdict_responder.json — the filteredEvent notification definition
• integrations/vendors/Suspicious/thehive/notifications/README.md — documentation: how the filter works, prerequisites, import steps in TheHive, and a link back to the responder

Verification performed

• ✅ Imported into a test TheHive instance and confirmed the notification triggers only on Case/Alert objects with an added suspicious:verdict= tag (no false trigger on tag removal or unrelated tags).
• ✅ Confirmed the responder runs end-to-end once triggered, updating the matching Suspicious investigation.
