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.
