[Bug] Type issue in vitest workspace

[Stanzilla]

Describe the bug

I'm using storybookNextJsPlugin in a vitest.workspace.ts file and it errors about a type miss-match.

Steps to reproduce the behavior

vite 6.2.3
vitest 2.1.9
storybook 8.6.11

import { defineWorkspace } from "vitest/config";
import { storybookTest } from "@storybook/experimental-addon-test/vitest-plugin";
import { storybookNextJsPlugin } from "@storybook/experimental-nextjs-vite/vite-plugin";
import { join } from "path";

import { resolveRoot } from "@company/tools-esm/helpers/paths";

const { MR_ID } = process.env;
const IS_CI = process.env.IS_CI || "false";

export default defineWorkspace([
  {
    extends: "./vite.config.mts",
    plugins: [
      storybookTest({
        // This should match your package.json script to run Storybook
        // The --ci flag will skip prompts and not open a browser
        storybookScript: "yarn storybook --ci",
        storybookUrl: (() => {
          if (IS_CI !== "true") return "http://local.company-stage.com:9002";
          return MR_ID
            ? `https://storybook-web-next-${MR_ID}.company-stage.com/`
            : `https://storybook-web-next.company-stage.com/`;
        })(),
      }),
      storybookNextJsPlugin({
        dir: join(resolveRoot(), "projects", "web-next"),
      }),
    ],
    test: {
      name: "storybook",
      // Enable browser mode
      browser: {
        enabled: true,
        name: "chromium",
        // Make sure to install Playwright
        provider: "playwright",
        headless: true,
      },
      // Speed up tests and better match how they run in Storybook itself
      // https://vitest.dev/config/#isolate
      // Consider removing this if you have flaky tests
      isolate: false,
      setupFiles: ["./.storybook/vitest.setup.ts"],
    },
  },
  {
    extends: "./vite.config.mts",
    test: {
      include: ["./**/*.test.ts"],
      name: "unit",
      environment: "node",
    },
  },
]);

Expected behavior

No error
