SpringBoot Java version sticks to 11 when choosing kotlin on start.spring.io

When the combination of Spring-Boot 2.6.0, Language Kotlin and Java 17 is selected on start.spring.io in the generated pom.xml the property java.version is still configured to 11. According to the Kotlin docs JVM target 17 is supported in Version 1.6.0, see https://kotlinlang.org/docs/whatsnew16.html#kotlin-jvm.
