Publish v3 to npm

[druvisc]

The npm package is outdated: https://www.npmjs.com/package/preload-webpack-plugin

Pre-requisites
This module requires Webpack 2.2.0 and above.

npm install preload-webpack-plugin --save-dev installs ^2.3.0, not the Webpack 4 compatible v3

[druvisc]

Use npm install preload-webpack-plugin@next --save-dev for Webpack 4

@jeffposnick What else needs to be done for v3 to make it into the master branch? It seems to work fairly well from the limited use I've tested it in.

Any news?

Is that possible to use @next version to webpack@5 directly?
