This matches the version we use in Nix, in keyserver/.nvmrc, keyserver/Dockerfile, and services/electron-update-server/Dockerfile.
It should fix a Buildkite CI error I initially saw in the following diff:
error lru-cache@10.2.0: The engine "node" is incompatible with this module. Expected version "14 || >=16.14". Got "16.13.2" error Found incompatible module.
