include webpack that is being used to the webpackFinal function

Is your feature request related to a problem? Please describe A clear and concise description of what the problem is. Ex. I’m always frustrated when […] it would be nice if when modifying webpack to pass the instance of webpack that is being used in storybook as part of the second parameter to webpackFinal so that you can destructure it to be something like:

webpackFinal: (config, { configType, webpack }) => {
....do stuff like webpack.DefinePlugin(...
return config;
}

@ndelangen not sure I understand. It is common if you are overriding or adding to webpack to require webpack in this file. What can happen is you may end up with 2 different versions of webpack, and it can cause pretty cryptic error messages. So if you are say just adding a variable via define plugin, this won’t work if there are multiple versions of webpack. How would the code you suggested help folks to use the webpack that storybook is also using? Can you maybe expand that idea further?
