docs: incompatible extract-loader is suggested

[4eb0da]

Documentation Is:

• Missing
• Needed
• Confusing
• Not Sure?

Please Explain in Detail...

https://github.com/webpack-contrib/css-loader#tostring

If, for one reason or another, you need to extract CSS as a plain string resource ...

extract-loader doesn't work with current version of css-loader, if css contains url(..)
This happens because css-loader produces new URL(...., import.meta.url), which cannot be parsed by outdated babel-core from extract-loader

Also, looks like extract-loader is deprecated with webpack v5 and should not be used

Your Proposal for Changes

Add a reminder about extract-loader current state or completely remove it from docs

You can use workaround - esModule: false, if you need extrac-loader, but I recommend to migrate on mini-css-extract-plugin
