Currently, it's setting nodejs16.x statically, so any serverless functions are deployed with Node.js v16.x regardless of the project's Node version setting:
https://vercel.com/docs/concepts/functions/serverless-functions/runtimes/node-js#node.js-version

This PR changes the behavior and starts producing the .vc-config.json file (for Vercel Build Output API) with the running OS's Node runtime version. This prevents Node version mismatch between build time and runtime.

@smaeda-ks Can we split auto detection part to merge new configuration sooner? πŸ™πŸΌ

kodiakhq bot pushed a commit to vercel/vercel that referenced this pull request Jan 31, 2023
This PR adds a few new environment variables for project settings.

This allows frameworks targeting the [Build Output API](https://vercel.com/docs/build-output-api/v3) to read data that is normally only available in through the `config` object when developing a [Builder/Runtime](https://github.com/vercel/vercel/blob/main/DEVELOPING_A_RUNTIME.md).

This will also solve the problem of old Builders/Runtimes that never passed the `config` through to `getNodeVersion()`.

I trust process.versions.node.split('.')[0] is expected behavior from vercel.. @styfle do you confirm too?

Looks good, thanks!

Lets try it out with a real deployment and try setting engines to see if that is respected.
