Updating node-themekit and TypeScript support

[DanPete]

Is there any way to manually update the node-themekit package to the latest release? 1.1.8

It has a few fixes for m1 mac in it.

Also, is there anyway to add TypeScript to the webpack config. I see the dev.config.js. Would it work to just add the plugin ts-loader plugin there and to the prod.config.js` too?

Also thanks for the great repos! 👍 I have used your webpack 4 themekit repo for a while, but ready to try out webpack 5! 🙂
