Update DevOps adoption metric tooltip
Summary
This is a follow-up of #296972 (comment 484903661)
With #289856 (closed) DevOps adoption metrics data will appear pretty soon after creation, so we need to update (or remove) tooltip here: https://gitlab.com/gitlab-org/gitlab/uploads/3e5507c26e6aa9d9dd99d3d2d0be4060/image.png
Suggestion
Remove the tooltip
