Add 'engines' declaration in all relevant package.json files

From #434 (comment)

Done is:

• The 'engines' declaration is added to the root package.json file and all 'package.json' files in the packages directory.

The required node.js version is:

{
  "engines": {
    "node": ">=16"
  }
}

I'm not sure about the required npm version, this would need to be checked.

Hi, i was trying to install deps on a node v17 and npm 8.6 and it turn out that it didn't works. I had to upgrading node up to 18.16.0 and npm to 9.5.1
