Update the On Demand DAST E2E spec
What does this MR do and why?
Update the On Demand DAST E2E spec
With DAST v5.0 using Browserker as a browser based test, use a different vulnerability to test against, as it turns out the previous used one was a proxy scanning false positive.
See discussion at https://gitlab.com/gitlab-org/gitlab/-/issues/461031#note_1900460408
Briefly investigated using DVWA - #461221 (closed) - however ran into the issue whereby it wants to run against localhost
which our runner cannot find (to scan against).
