Describe the bug

Nuxt has a schema of vue-loader options that partially matches vue-loader.

For example, you can enable experimental features like Vue 3.3 defineModel in webpack.loaders.vue, but TypeScript won't recognize it as a valid property. However, if you ignore the error squiggles, it does work.

'{ defineModel: true; }' is not assignable to type '{ productionMode?: boolean | undefined; transformAssetUrls?: { video?: string | undefined; source?: string | undefined; object?: string | undefined; embed?: string | undefined; } | undefined; compilerOptions?: { ...; } | undefined; }'.
  Object literal may only specify known properties, and 'defineModel' does not exist in type '{ productionMode?: boolean | undefined; transformAssetUrls?: { video?: string | undefined; source?: string | undefined; object?: string | undefined; embed?: string | undefined; } | undefined; compilerOptions?: { ...; } | undefined; }'.(2322)
