Fixes the trace-analytics-sample-app project and updates it. (opensearch-project#6350)

Use Gradle 9.2.1, the current latest. Update to Spring Boot 4.0.0. Updated to Java 21. Use a more fixed Docker image when building to avoid future build failures - always Gradle 9 and JDK 21.

Also, updates or adds copyright headers.
