What is the current behavior?
I've created a minimal bug repo repository that works fine with Webpack CLI v4 but fails with v5:
https://github.com/yvele/webpack-cli-repro-babel
To Reproduce
Steps to reproduce the behavior:
https://github.com/yvele/webpack-cli-repro-babel#build
Expected behavior
webpack.config.babel.js should be handled by Babel all the import way down. Same behaviour than Webpack CLI v4.
