feat: Bump minimum node.js version from 12 to 14.14.0

With nodecg-io 0.3.0 node.js 14 or higher is required for development
installations. This minimum version is required by the husky
dependency but I think some other dependencies also want node.js 14+.

I think it is reasonable to bump the minimum supported node.js version
to 14 now. Most people should be able to upgrade to node.js 14 without
any problems.

Updates the check at cli startup to require node.js 14 and also updates
node.js version in the GitHub Actions CI configuration.
