[Bug]: @storybook/react-webpack5 framework cannot build libraries in monorepo

[mandarini]

Describe the bug

I have a Nx monorepo, with one application and some libraries. When I am using @storybook/react-webpack5 framework, it works for the app but it does not work for the libraries, whether they are buildable or not. @storybook/react-vite works in all cases. Whereas @storybook/react-webpack5 seems to only work with projects that are built with webpack.

Closing this, as installing core-js fixes it.
