fix: force nodejs 12

[slorber]

I couldn't make this repo run by default on Netlify without downgrading Node.js versions.

14/16 didn't work, but 12 worked

I suggest specifying a version so that others trying to deploy it do not have to figure things out

I think the intent here is good but unfortunately the code doesn’t quite work—I don’t believe that you can set environment variables for aws lambda/netlify functions via your netlify.toml

https://answers.netlify.com/t/netlify-functions-and-env-variables-from-netlify-toml/4404/28

These need to be set in Netlify UI instead—which unfortunately means will require an additional README step.

Thank you for the report!
