Describe the bug

When using Vitest 4 with Nuxt, it shows warning on execution.

The Vitest environment nuxt defines the "transformMode". This options was deprecated in Vitest 4 and will be removed in the next major version. Please, use "viteEnvironment" instead.

Also, there is peer dependencies issue:

.
├─┬ @nuxt/test-utils 3.20.1
├── ✕ unmet peer vitest@^3.2.0: found 4.0.6
└─┬ vitest-environment-nuxt 1.0.1
  └─┬ @nuxt/test-utils 3.20.1
    └── ✕ unmet peer vitest@^3.2.0: found 4.0.6

Here the transformMode option used instead of viteEnvironment
