Revert "Merge branch 'renovate/nodejs-version' into 'main'"

@marcel.amirault The asdf-nodejs plugin doesn't yet support this version, but it should pretty soon:

$ asdf plugin update nodejs
Updating nodejs to master
Already on 'master'
Your branch is up to date with 'origin/master'.

$ asdf install nodejs 18.14.1
Trying to update node-build... ok
node-build: definition not found: 18.14.1

We need to manually test these locally with make setup. It usually takes a few days for asdf-nodejs to catch up. It might just be bad timing that this MR got raised right on a new release of Node.js.
