Upgrade to css-minimizer-webpack-plugin 5

Hey packagers!

This release upgrades the css-minimizer-webpack-plugin from 4 to 5. While this dependency bump is a major bump, the underlying library had very few breaking changes and the fast majority of users should be completely unaffected by this.

Upgrading

Run:

npm install "@symfony/webpack-encore@^4.4.0" --save-dev

Or:

yarn upgrade "@symfony/webpack-encore@^4.4.0"

Changes: v4.3.0..v4.4.0

Happy Packing!
