Describe the bug

After adding @nuxt/test-utils/module to nuxt.config.ts, the vitest.config.ts file in the root directory is not automatically loaded. Even when explicitly specifying vitestConfig.config in the testUtils property, the vitest.config.ts is not being applied.

Here is the configuration:

// nuxt.config.ts
export default defineNuxtConfig({
  devtools: { enabled: true },

  modules: [
    '@nuxt/test-utils/module'
  ],

  testUtils: {
    startOnBoot: true,
	logToConsole: true,
    vitestConfig: {
      // config: path.join(__dirname, 'vitest.config.ts') // not working
    }
  }
})

// vitest.config.ts
import { defineVitestConfig } from '@nuxt/test-utils/config'

export default defineVitestConfig({
  test: {
    globals: true,
    silent: true,
    environment: 'nuxt',

    include: [
      'server/**/*.test.ts',
    ],

    exclude: [
      '**/-*.*',
    ],
  }
})

I have observed a difference in the results when running tests directly with vitest and running them via nuxt dev.
