Subject: [PATCH] KE2: Use the right language version

With this, if I make the testsuite driver use 1.7, then the test code

sealed interface ReadResult
data class Number(val number: Int) : ReadResult
data class Text(val text: String) : ReadResult
data object EndOfFile : ReadResult

makes the extractor print
