Seems reasonable, but there are lots of webpack deps across different storybook packages and they all resolve to 4.32.2 (currently), so what exactly does it accomplish?

[christophehurpeau]

We use create-react-app so react-scripts has its own webpack version lower than storybook. This is the one that's in the root node_modules, and both @storybook/core and @storybook/react have a webpack version in their node_modules, and they have different versions. That mean we have 3 webpack versions and it felt wrong.
We could update all dependencies with yarn upgrade to make sure all dependencies are to the latest possible version, but I'm guessing we're not the only ones in this case
