Add false positive alert to Vulnerability Details

What does this MR do and why?

This MR is part of the pipeline's security tab's migration to GraphQL.

Going forward the VulnerabilityDetails component will be shared between the vulnerability detail's page (accessible via "Security & Compliance" -> "Vulnerability Report" -> Details for a given vulnerability) and the pipeline tab's vulnerability modal.

The modal currently renders an alert if the given finding has been flagged as a false-positive. This MR adds this to the VulnerabilityDetails component.
