Follow-up from !223012: Add product category - import vol. 1 **Context:** `config/metrics/**/*.yml` define internal metrics with associated product group and feature category. Many of the integration metrics are assigned to ~"group::import", but more correctly belong to other groups. The related MR spawned [this discussion](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/223013#note_3078683260) around whether to re-assign the product group. https://handbook.gitlab.com/handbook/product/cross-stage-features/ **Objective:** Ensure all integration metrics are correctly attributed to the groups that now own them following the product category reorganization. **Related:** - !223012 Add product category - import vol. 1
