Is your feature request related to a problem? Please describe.
Our app Dockerfile uses Node 16, and Node 22 just came out last week. As a first step, we'll bump the version of Node to 18 in #1792. Then we'll bump it to 20.

Describe the solution you'd like
Hopefully everything still runs correctly with Node 20.

Describe alternatives you've considered
None. We may be falling behind on PHP versions, but we want to keep current on Node.

Additional context
We'll eventually want to go to Node 22, as long it doesn't require major rewrites.
