[Problem] 如何使用 settings.gradle.kts 接入？

在文档那里，接入部分
```gradle
setBinding(new Binding([gradle: this]))
evaluate(new File(
settingsDir.parentFile,
'flutter_module/.android/include_flutter.groovy'
))
include ':flutter_module'
project(':flutter_module').projectDir = new File('../flutter_module')
```

这是 settings.gradle 的代码，但是我用的是 settings.gradle.kts ，我试着
```kotlin
val flutterModulePath = File(settingsDir.parentFile, "flutter_module/.android/include_flutter.groovy")
apply {
from(flutterModulePath)
}
```

可是我发现 kts 无法 evaluate groovy 文件，这可怎么办呐

Start with the documented settings.gradle integration and compare it with the reported settings.gradle.kts attempt. Read the referenced flutter_module/.android/include_flutter.groovy file and determine how the integration should be documented for Kotlin DSL users. Done means the documentation explains a working settings.gradle.kts path or clearly states the supported limitation.
