Add Gradle build support to load-super-heroes

The Gradle variant of the workshop references ./gradlew build for
load-super-heroes, but the project only had a Maven pom.xml. Added
build.gradle.kts, settings.gradle.kts, gradle.properties, and the
Gradle wrapper so the Gradle workshop instructions work correctly.
