Add request-URL 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 request.url or a URL constructed by location.hostname and location.path. This MR adds this to the VulnerabilityDetails component.

2. Run the pipeline on master, wait for it to complete
3. Within the imported project go to "Security & Compliance" -> "Vulnerability report" -> click on a DAST vulnerability (tip: use the "Tool" filter to find these)
4. Verify that the URL shows up
5. Without the change that the patch introduces, it should not render
