Additional Details Documentation Not Linked

As a result of recent updates to the NarUnpacker class, additional details documentation is not linked from component documentation pages.

The documentation generator depends on the existence of the additionalDetails.html at a specific location in the documentation work directory. The NarUnpacker is responsible for reading NAR files processing JAR files to find an extract documentation files based on an expected relative path in the JAR containing the component class. Adjustments to the unpack processing to reuse a shared JAR file entry method resulted in failing to find the expected relative path. Without the matched relative path, the NarUnpacker does not extract JAR file entries containing the additional details documentation.
