update to webpack 5

[dgaidula]

I've been using wp-webpack-script for the last 6 months and loving it. I'm curious if there are plans to update it to use WP 5.

It's so bad that such a good project is abandoned

Hi, I do have plans to upgrade to webpack 5 and also explore ESBuild over babel. But unfortunately it won't happen anytime soon :)

We're using wpack for more that 2 years and it just great.
But webpack4 is breaking my project now. I need to migrate to node v18+ and it does not work with webpack4...
