Javascript compilation error blocking new release

[knadh]

I'd just pushed the v2.4.0 release when the Javascript compilation failed in the GitHub Actions environment.

error eslint-import-resolver-webpack@0.13.1: The engine "node" is incompatible with this module. Expected version "^16 || ^15 || ^14 || ^13 || ^12 || ^11 || ^10 || ^9 || ^8 || ^7 || ^6". Got "18.11.0"

Looks like Node has been updated in the GH Actions environment. I checked my local version and it was Node 14 on Fedora 33 (whoops). Upgraded to Node 18.5 and it fails to compile locally, as expected.

I tried upgrading the dev dependencies and it immediately showed signs of a nightmarish rabbithole worse than this, so any help is greatly appreciated!
