Mix no longer minifies js moved with copyDirectory

[jhjvandenbroek]

• Laravel Mix Version: 6.0.49
• Node Version: v20.5.0
• NPM Version (npm -v): 9.8.0
• OS: Mac OS

Description:

In 6.0.43 this used to minify when running npm run prod. with 6.0.49 the files are not minified

EDIT: Apparently this was changed in this PR:
#3256

Steps To Reproduce:

Use something like this in webpack.mix.js:

const mix = require('laravel-mix');

/*

mix.js('resources/js/app.js', 'public/js')
    .sass('resources/sass/app.scss', 'public/css')
    .copyDirectory('resources/js/custom/pages', 'public/js/pages')
    .version();
