Feature description

The Windows bot currently runs Node.js 20.14.0 according to http://54.193.163.58:8877/932126281d279f8/output.txt, which causes a warning to be logged. The Linux bot most likely also runs Node.js 20, but perhaps a slightly newer minor version, causing said warning to not appear there.

Node.js 20 used to be the active LTS version, but according to https://nodejs.org/en/about/previous-releases Node.js 22 is the active LTS now.

The Windows bot also logs that it uses NPM 8.14.0 which is also fairly old by now.

We should update the Windows and Linux bots to newer versions of Node.js and NPM, equal versions on both bots to avoid differences, which should be Node.js 22.16.0 (the most recent LTS version) and a corresponding modern NPM version.
