[olyagpl]

1. Add a demo test for https://www.graalvm.org/latest/reference-manual/native-image/guides/use-sbom-support/
2. Add a demo test for https://www.graalvm.org/jdk24/security-guide/native-image/sbom/#including-class-level-metadata-in-the-sbom
   The continuation of [GR-60094] Native Image Public Demos Status Review and Refactoring. Part 1 #300.
   The goal is to sort the demos by categories (Native Image, referenced from blog posts, archived, etc.)

This step will pass with the new EA build available. Currently it's on 24.ea.22-graal. We need 24.ea.23-graal for the new option --enable-sbom=class-level to become available.
