Scope function with nested forEach can be simplified

Reports forEach functions in the scope functions such as also or apply that can be simplified.

Convert forEach call to onEach quick-fix can be used to amend the code automatically.

Examples:

fun test(list: List<Int>) { val x = list.also { it.forEach { it + 4 } }.toString() val y = list.apply { forEach { println(it) } } }

After the quick-fix is applied:

fun test(list: List<Int>) { val x = list.onEach { it + 4 }.toString() val y = list.onEach { println(it) } }
