[DevOps Adoption] Page constantly refreshes

Summary

The DevOps Adoption page constantly refreshes every 60 seconds.

Steps to reproduce

Go to https://gitlab.com/groups/gitlab-org/-/analytics/devops_adoption?tab=dev and let the page sit there for a while. Observe that it continuously refreshes every 60 seconds.

Proposed solution

Refactor the logic of the frontend data polling to refresh the data if the data is from the previous month (currently previous day) or there is pending data.
