Add link to Time to restore service chart

Merged Magdalena Frankiewicz requested to merge fix-time-to-restore-service-link into master

Solves #365919 (closed).

This MR adds link to CI/CD Analytics Time to restore service tab from Value Stream Analytics page. Before clicking Time to restore service on Value Stream Analytics page would redirect to documentation. Since we have CI/CD Analytics Time to restore service chart now, we should link there.
