Add exception to @devup-ui/no-useless-responsive when using globalCss imports

```js
globalCss({
  imports: [
    'https://cdn.jsdelivr.net/npm/quill@2.0.3/dist/quill.snow.css layer(t)', 
  ], // Responsive are useless. Remove them.eslint(@devup-ui/no-useless-responsive)
})

```

Currently eslint throws error when you use an array with only one element, but there needs to be an exception when you use `imports` property in `globalCss`.
