Onboarding: Fix manager dist reference

    getAbsolutePath("@storybook/addon-onboarding"),
    getAbsolutePath("@storybook/addon-links"),
    getAbsolutePath("@storybook/addon-essentials"),
    getAbsolutePath("@chromatic-com/storybook"),
    getAbsolutePath("@storybook/addon-interactions"),
  ],
  framework: {
    name: getAbsolutePath("@storybook/react-vite"),
    ///...
