* build(js): remove yarn.lock
Yarn had changed its methods of packaging long ago and it hasn't been supported ever since. It's much better and easier to just use the original NPM.
* fix(docker): change yarn to npm command
* doc(README): change yarn mentions to npm
* fix(docker): use npm ci instead of npm install
* build(package-lock): update js dependencies
* build(docker): use node:20 image when building
