### Problem
The "Product Intelligence" group has recently been renamed to "Analytics Instrumentation", see https://gitlab.com/gitlab-com/www-gitlab-com/-/merge_requests/122009. While the main labels have already been renamed there are still quite a few places where we still need to change the name. Some of these places might be straight-forward. Others won't. This epic is here to collect all places where renaming still needs to happen and house issues for those.
### Result
All places, that are feasible should use "Analytics Instrumentation" instead of "Product Intelligence"
### Places to rename
- Handbook pages
- Product Intelligence Review process (Dangerbot + labels)
- Main "Product Intelligence" label
- This group: https://gitlab.com/gitlab-org/product-intelligence and our group in the section https://gitlab.com/gitlab-org/analytics-section/product-intelligence (do we need both?)
- Any mention in Sisense charts and some charts themselves (if they depend on our label)
- [Retrospective project](https://gitlab.com/gl-retrospectives/product-intelligence) and automatized retro issues (currently they're using old labels to find issues that have been shipped/slipped - [example](https://gitlab.com/gl-retrospectives/product-intelligence/-/issues/39))
- Update Workday group
- Product Intelligence Office Hours meeting name and bot handle
- Personal profiles of team members - eg. Gitlab, Zoom, Slack profiles, email signatures
