Uncomment the package-info.java workaround when OpenJDK has fix

[SachinMali]

Upon opening PRs to main the Maven CI github action fails with the below error

  Error:  Failed to execute goal org.apache.maven.plugins:maven-javadoc-plugin:2.9.1:jar (attach-javadocs) on project aem-guides-wknd.core: MavenReportException: Error while creating archive:

Root Cause is [Javadoc does not handle package annotations correctly on package-info.java]
(https://bugs.openjdk.org/browse/JDK-8222091)

To fix above issue PR openjdk/jdk11u-dev#1475 is raised but not merged and released..

Work Around is to skip the Java Version by adding empty JavaDoc block like

/** */@org.osgi.annotation.versioning.Version("2.1.0")
package com.adobe.aem.guides.wknd.core.models;
