Add all fields that are needed to render the Vulnerability Details page to the GraphQL schema

In order to fully migrate the Vulnerability Details page to GraphQL, we need to add the following fields to the Vulnerability type's schema.

Below is a list of the data-fields that we currently use to render a Vulnerability, matched against the current Vulnerability schema (✅ are fields that are already supported / 🛑 are fields that are missing):
