Audit spacing between assembly

[jordanpagewhite]

The spacing between assemblies/components is currently inconsistent and does not match the Marvel designs. I will copy/paste a Slack comment from Gina here:

I thought about each assembly getting a bottom padding of 32px. (so they don’t receive top paddings). Then for assemblies with a background, they’d have 24px padding between content and background but it doesn’t look that way bc of the background starting at the same distance of 32px from the last assembly

and also you can review the /openshift mockup in Marvel for guidance.
