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.

Beginne mit der Konfiguration von referencedLibraries und reproduziere die fehlende Dokumentation, indem du nach dem Entfernen von META-INF/maven eine Klasse importierst und Hover oder Ctrl+click verwendest. Erledigt ist es, wenn Benutzer ein Javadoc JAR einer referenzierten Bibliothek zuordnen und dessen Dokumentation per Hover anzeigen können.
