Output remote Node version

[janpio]

Currently our setup outputs the local node version used to build and run a project.
But for Netlify and Co it does not output the remote version that is used to a) build the project and b) run the project (on Lambda).
Both of these are interesting and relevant as it could influence the experience a user has.

As simple as adding this to the returned body:

nodeVersion: process.versions.node,

That would be nice indeed, but we will not be able to do an exact string matching anymore as this version could change anytime. (For example, when there is a Node.js patch)
Just adding this because it needs to be considered when outputting it in the current test setup.
