Subject: [PATCH] build: set minimum Node.js version to 12.13

This change provides an improved performance baseline as well as access to newer Node.js APIs and Javascript language features which the Angular CLI will now be able to leverage.

BREAKING CHANGE:
Node.js version 10 will become EOL on 2021-04-30.
Angular CLI 12 will require Node.js 12.13+ or 14.15+. Node.js 12.13 and 14.15 are the first LTS releases for their respective majors.
