Enhance precision of the vulnerability detection POC documentation

[Rebits]

Description

Due to the Vulnerability Detection refactor, the associated proof of concept documentation changed accordingly. However, the current Proof of Concept (POC) provided lacks sufficient clarity and detail regarding the behavior of the module and how to obtain the presented results. Specifically, the section on Visualizing the alerts is incomplete, as it fails to trigger alerts without the installation of a vulnerable package in an already running environment. This behavior is further elaborated upon in issue #21659.

Moreover, there is a notable absence of information pertaining to the inventory, dashboard, or various use cases such as identifying new vulnerabilities, upgrading vulnerable packages, or removing vulnerable packages.

To address these shortcomings, it is proposed to reorganize and introduce new sections to fully elucidate the module's potential. These additions should encompass all necessary instructions to enable users to replicate the POC effectively.
