https://github.com/facebook/create-react-app/issues/9886 was a crippling performance regression that rendered react-scripts close to unusable, at least for all my projects where I was using it.
Fortunately, this performance regression was fixed by the following release of eslint-webpack-plugin: https://github.com/webpack-contrib/eslint-webpack-plugin/releases/tag/v2.4.1 (otherwise I would have been forced to downgrade to react-scripts 3.X).
However, the performance regression was only fixed for new users of react-scripts, but not for existing users.
The problem is that the internal dependency to eslint-webpack-plugin still accepts broken versions it its admissible range of versions.
Therefore, existing users are forced to read through https://github.com/facebook/create-react-app/issues/9886 until they find out that they either have to manually bump eslint-webpack-plugin or delete their entire package-lock.json and re-install everything from scratch.
So this PR is an attempt to fix the performance regression for all users that are updating react-scripts, instead of waiting until they read through GitHub bug reports or delete their package-lock files.
