Bug Kotlin: functional interface can not be handled

[mylinhdao]

The following code of functional interface cannot be parsed correctly by tree-sitter-kotlin, which cause to uncorrect calculation of "classes", "functions" and "complexity" metrics:

fun interface IntPredicate {
    fun accept(i: Int): Boolean

There is already a PR for this in fwcd/tree-sitter-kotlin#103 .
As soon as this is merged and released, we need to adjust node-type-config.json
