Refactor redundant divs on Kubernetes apps page

What does this MR do?

On the Kubernetes applications list, each application has an <application-row> that uses a <template #description>, where every template's first child is a <div>. Rather than repeat this for every application, this MR moves the div into the <application-row> component.

Note that this MR is easier viewed by unchecking "Show whitespace changes":
