Javadoc support for referencedLibraries?

If a non-maven/gradle library is added to referencedLibraries config (added by https://github.com/redhat-developer/vscode-java/pull/1196) - it is impossible to add the library's javadoc.

Environment

• Operating System: Tried OSX and Gentoo Linux.
• JDK version: 19
• Visual Studio Code version: 1.76.0
• Java extension version: v0.25.8

Steps To Reproduce

1. Download any library from maven, e.g. https://repo1.maven.org/maven2/com/pelzer/util/pelzer-util/1.9.0/pelzer-util-1.9.0.jar and https://repo1.maven.org/maven2/com/pelzer/util/pelzer-util/1.9.0/pelzer-util-1.9.0-javadoc.jar
2. Delete META-INF/maven from the jar
3. Add two jars as referenced libraries to settings.json
4. Import a class and hover over it or ctrl+click on it. Only bare decompiler structure shows up without documentation.

Current Result

Import a class and hover over it or ctrl+click on it. Only bare decompiler structure shows up without documentation.

Expected Result

Ability to map javadoc jars to libraries to allow for javadoc presentation on hover.

referencedLibraries の設定から始め、META-INF/maven を削除した後にクラスをインポートし、hover または Ctrl+click を使って不足しているドキュメントを再現します。ユーザーが Javadoc JAR を参照ライブラリに関連付け、hover でそのドキュメントを表示できれば完了です。
