Clearer, Real-Time Slack Alerts Updates for Monitor Resolutions

Slack integration was improved to support automatic messages updates. Whenever a monitor returns to an OK state, the original Slack alert message now updates in real-time to reflect the resolution, keeping everything clear and up to date.

This enhancement ensures your team instantly sees when issues are resolved, reduces channel clutter, and keeps everyone aligned without extra effort. Stay focused and responsive with more efficient incident communication in Slack!
