Use Property API for extension configuration

expected:
```kts
val printBuildHealthProperty: Property = TODO()

dependencyAnalysis {
reporting {
printBuildHealth = printBuildHealthProperty
}
}
```

actual:

```kts
val printBuildHealthProperty: Property = TODO()

dependencyAnalysis {
reporting {
printBuildHealth(printBuildHealthProperty.get())
}
}
```

We would like to avoid the `.get()` - thanks!

Start at the dependencyAnalysis reporting configuration and the printBuildHealth API shown in the issue. Trace how the reporting option is configured, then verify that assigning a Property works without calling get(); done means the expected Kotlin DSL usage is supported.
