[Bug]: Show missing `vite.config.js` file in migration notification while the `vite.config.ts` exists

[SinaKarimi7]

Describe the bug

I have a project with React/TypeScript/Vite and I have added the Storybook for a while. Now I want to upgrade the dependencies and enter this command based on storybook documentation:

pnpm dlx storybook@latest upgrade

I just realized from the banner that the migration script was unable to locate the vite.config.js at the root of my project. This is accurate because I don't have a .js file. Instead, I have the TypeScript version of the vite.config.

As a user, I saw this banner and I assumed this file doesn't exist in my directory. So if this banner shows by default (no matter whether the user has the file or not) this is a UX/DX issue. Maybe it will be better to have a more clear description/content in this banner.

Additional context

I was using storybook version 8.1.1 and I got to this banner in the middle of running the upgrade script (pnpm dlx storybook@latest upgrade)

But my package.json file was changed in the meantime.

Hi @SinaKarimi7 how do I reproduce at the given link?

[crrobinson14]

Also note: the link referenced in this warning is not valid and leads to a 404: https://storybook.js.org/docs/8.0/migration-guide/#missing-viteconfigjs-file

This is the right one, possibly? https://storybook.js.org/docs/migration-guide/from-older-version#missing-viteconfigjs-file

But that page is not very helpful, it just links to https://github.com/storybookjs/storybook/blob/next/MIGRATION.md#framework-specific-vite-plugins-have-to-be-explicitly-added

which itself seems to cover the required cases, but not in a "just do this to fix that warning" kind of way. It talks through adding framework plugins which sound like optional add-ons, not base features, leaving one wondering if you actually need to do it or not (since SB does run without it - will adding this file break me?)

How does one file a repro for a documentation issue?
