Implement 'is asked on same page as previous question' attribute on Duo Chat user questions
Description
Now that we are capturing the URL that the question is asked from in Duo Chat, we should add the 'is asked on same page as previous question' to the attributes we track.
Follow-up work from issue https://gitlab.com/gitlab-org/gitlab/-/issues/430975 (implementing attributes) and #435290 (closed) (capturing url).
