Update MR Summary feature to use `duo-user-feedback` component
At the moment, we have several AI features using different User Feedback mechanisms. [MR Summary](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/assets/javascripts/merge_requests/components/summary_note.vue?ref_type=heads#L5) is one of them. In the course of https://gitlab.com/groups/gitlab-org/-/epics/12971+, it is suggested to assess the use of [the standard, up-to-date `GlDuoUserFeedback` component](https://gitlab-org.gitlab.io/gitlab-ui/?path=/docs/experimental-duo-duo-user-feedback--docs) instead of [the outdated one](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/app/assets/javascripts/ai/components/user_feedback.vue?ref_type=heads).
