Expose option to configure react-docgen plugin

[flugg]

Is your feature request related to a problem? Please describe.

When I'm using the react-docgen plugin to auto generate controls for my stories I don't have access to any prop types that's imported from external modules. I'm using React Aria to build my UI library and a lot of the props are already exported by them so I don't want to have to duplicate them in my own components just to make Storybook pick them up.

Describe the solution you'd like

When using the react-docgen-typescript plugin we can use the reactDocgenTypescriptOptions to configure it. Could we expose a similar reactDocgenOptions to configure the react-docgen plugin?

Particularly I'm interested in removing the default exclusion of node_modules here:

storybook/code/frameworks/react-vite/src/plugins/react-docgen.ts

Line 37 in 70e70e7

exclude = [/node_modules\/.*/],

Describe alternatives you've considered

I tried to configure the viteFinal option in main.ts to update the plugin, but couldn't get it to work and the react-docgen plugin is not exposed in the @storybook/react-vite package it seems, so no easy way to replace the plugin without recreating it from scratch.

Are you able to assist to bring the feature to reality?

yes, I can

Additional context

Not sure of the best way to tackle this as I'm not too sure of the inner workings of Storybook, but I'm willing to attempt to fix the issue if it's something you believe will fix the issue and improve the project.
