Fix reports not propagated to detekt task with type resolution

[picklebento]

Configuring detekt gradle extension as below does not actually generate SARIF reports when running detekt<SourceSet> like :detektMain. The problem here is that we are merely not passing the reports in DetektExtension to reports of Detekt as a gradle task.

detekt {
    reports {
        sarif.enabled = true
    }
}

In addition to integration testing, I also manually verified through a sample project that the above is working.
