Explain why the Java version was capped at 24 for Kotlin modules

Recipe IDorg.openrewrite.java.migrate.CommentJava24KotlinCapArtifactorg.openrewrite.recipe:rewrite-migrate-java

Adds an explanatory comment to Maven pom.xml files in modules that were held at Java 24 because they compile Kotlin and depend on kotlin-stdlib older than 2.3, which cannot target Java 25 bytecode. Only modules whose resolved kotlin-stdlib is older than 2.3 are commented; the comment names that kotlin-stdlib version and the next step needed to reach Java 25. Self-healing: the comment is added while the module is at Java 24 and removed again once the module reaches a higher Java version (for instance after its Kotlin was upgraded to 2.3), so it only ever remains on modules that truly stay at Java 24 — whether a Kotlin 1.x cap or a 2.0-2.2 module whose Kotlin upgrade could not be applied. Intended to run last, scoped to modules that compile Kotlin.
