Use HTTP/2

Should speed up delivery of the many SVG files.

You can see this using the Google Lighthouse tool as well:

Figure 1: Production.

---

Figure 2: Dev server.

You can see that the numbers are mostly the same, although the dev server currently gets a "Performance" score of 87 (versus 84 on production), which I think is because the dev server was arbitrarily ~300ms faster on render.

@akuckartz put send behind a load balancer that supports HTTP/2 (Application Load Balanacer in AWS, Google Load Balancer in GCP)
