java: Add AI-generated XAML activity docs for Java package [STUD-79290]

[AlexMarinescuUiPath]

What changed?

Added structured markdown documentation for all six Java activities plus a package overview:

• \ConvertJavaObject.md\ - inputs, outputs, and XAML example for type conversion
• \CreateJavaObject.md\ - constructor arguments, class name, scope reference
• \GetJavaField.md\ - field access, type handling, output binding
• \InvokeJavaMethod.md\ - method invocation, argument list, return value
• \JavaScope.md\ - scope lifecycle, JAR loading, connection management
• \LoadJar.md\ - JAR path, classpath configuration
• \overview.md\ - package-level summary, activity index, usage guidance

All files live under \UiPath.Java.Activities.Packaging/docs/\ and follow the per-activity reference format (inputs, outputs, configuration, valid combinations, copy-paste XAML examples).

Why?

These docs are required to support LLM CLI tooling (Claude Code and similar agents) that need structured, machine-readable activity references to assist users working with the Java package. Generated and verified as part of STUD-79290.
