feat(quiz_java): Java port of quiz app using codedifferently-instructional

[dev-benson-03]

Summary
Quiz questions completed and answered fully
Java port of the quiz assignment in lesson_02/quiz_java, wired to the
lib/java/codedifferently-instructional library.

Changes

• Added Lesson2.java (builds questions + prints quiz via library)
• Updated App.java to run Lesson2
• Added tests: AppTest.java, Lesson2Test.java
• Gradle config:
  i) Included modules in settings
  ii) App depends on :codedifferently-instructional:instructional-lib

Notes/Problems (I'm trash as ever at Java)
I had two Gradle worlds: a nested build under lesson_02/quiz_java (include("quiz_java")
{ projectDir = file("app") }) and the top-level repo. Running Gradle inside the nested build
made it blind to the library, so dependency lookups failed.

I initially referenced the library by the wrong project path
(e.g., :lib:java:codedifferently-instructional). The library is multi-module;
the actual compile target is :codedifferently-instructional:instructional-lib.
Once I included that exact project in settings.gradle.kts, the dependency resolved.

I mixed up filesystem paths vs Gradle project names. Gradle dependencies are by project name declared in settings.gradle.kts, not by folder path.

You also need to make the updates to the typescript app as well.

Nevermind, I see what's going on. I'll submit this PR.
