Use engines.node as source of version data for actions/setup-node action

The actions/setup-node GitHub Actions action is used to set up Node.js in the GitHub Actions runner machine.

The action supports obtaining the Node.js version to set up from the `engines.node` field of the package.json file.

This allows us to define the standardized version of Node.js for use by project contributors in a single place rather
than having to maintain multiple instances of that data.
