Show review app link in MR even when deployment is running
Problem to solve
At the moment, you are able to click on a handy link to view the latest review app, which is a great frequently used feature especially if your role involves doing lots of reviews.. QA, product, business analysts, etc. This is how the feature appears today when your pipeline has completed and the review app is available:
One issue, though, is that if someone starts a new deployment the link to the latest review app disappears. The old one is still there and running (at least in normal cases) and there's still value to seeing the last version, with the affirmative understanding that it's actively being updated.
In busy merge requests, you may vary rarely or even never see the review app link unless this is changed.
Instead of making the review app link disappear, it should still display a link to the currently running older review app along with a warning that a new deployment is already underway.
