[pereyra-m]

Closes #7124 , wazuh/wazuh/issues/22532

Description

This PR improves the step-by-step guide for vulnerability detector and the its connection with the indexer nodes:

• More details were added for multi-node environments. Also, the same words and expressions than the Filebeat section were used to improve consistency

• The start of the manager was moved after the certificates deployment to avoid warning messages during the installation

Checks

Code formatting and web optimization

• Uses three spaces indentation.
• Adds or updates meta descriptions accordingly.
• Updates the redirects.js script if necessary (check this guide).

Writing style

• Uses present tense, active voice, and semi-formal registry.
