Default (runtime) Node.js version

Describe the feature

To ensure all deploy providers behave uniformly, we should export a defaultNodeVersion utility to be used within the presets as a fallback.

See this comment for reference.

This is such a nice idea to think about a generic option to configure node runtime version.

However since the range of supported versions across providers differs, i would suggest by first normalizing this for each provider (was, firebase) and then see how we can generalize it.
