Upgrade Min Node Version

[budparr]

Was getting an error on Netlify

Error: Error building site: POSTCSS: failed to transform "style.css" (text/css): (node:1836) ExperimentalWarning: Readable[Symbol.asyncIterator] is an experimental feature. This feature could change at any time
5:35:41 PM: TypeError: Object.entries(...).flatMap is not a function...

To fix, I updated the NODE version in netlify.toml

NODE_VERSION = "12.13.0"

as per https://tailwindcss.com/docs/upgrading-to-v2#upgrade-to-node-js-12-13-or-higher

I'd update it, but not sure if there are implications elsewhere.
