Describe the bug

I am using ESLint version 9.2.0 in a Nuxt 3 project. When running ESLint, it throws a ConfigError indicating that the "import" plugin is being redefined. This issue occurs even after following the recommended setup and ensuring that the plugin is not explicitly defined multiple times in my configuration.

This started happening after updating the nuxt eslint module.

Well... the reproduction is there. Just copy the configs and paste them into the eslint.config.js file in any nuxt 3 project :/
