[Bug]: Issues With Vitest Default Config

[mindingdata]

Describe the bug

When I create a new project, with nothing in it, and install the Storybook Vitest plugin, it has an issue escaping characters.

Run npm create vite@latest to create a new React project, with Typescript
Run npx storybook@latest init to install Storybook over the top
Run npx storybook add @storybook/experimental-addon-test to install the new test runner
Edit your project.json to have a test command that runs "vitest" as per documentation

Run "npm run test".

You should see an error like so :

TypeError: Failed to fetch dynamically imported module: http://localhost:63315/@fs/C:/Projects/PlainStorybook/vite-project/.storybook%0Bitest.setup.ts?import&browserv=1731025020823

The %0B in the middle of that was interesting and is a null byte. So I searched "itest.setup" in my project and in the vitest.workspace.ts file that is created by default, it has that and a subtle escaping issue seems to be occurring :

If I double backslash this, I can move past this error.
