Vulnerability Detector - Improve alert generation documentation

[sebasfalcone]

Description

We noticed that users have recurrent questions regarding alert generation. It seems like the documentation is not clear enough on how and when the alerts are generated

We need to update the alert generation documentation to better reflect alert generation scenarios

Note

Users tend to restart the agent expecting for alerts to be generated when this is not the case.

DoD
