Prevent layout shift on `Duration`
Created by: courier-new
I noticed the Duration component was causing layout shift if the time displayed was actively changing (e.g. in Batch Changes land while a batch spec is actively executing). This gives it a fixed width by letting an element with a static, filler time determine the parent width and then absolutely positioning the actual time over top of it.
Test plan
Added storybook coverage for this component to demonstrate the effect.
