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 in #1793. And then we'll bump it to 22.

Describe the solution you'd like
Hopefully everything still runs correctly with Node 22.

Describe alternatives you've considered
Staying on Node 20 if 22 would require major rewrites.
