Replace parsed Java docs with link on class level

e.g.

package org.openehr.rm.ehr_extract.common;

import java.lang.Boolean;
import java.lang.Object;

/**
 * @see <a href="https://specifications.openehr.org/releases/RM/Release-1.1.0/ehr_extract.html#_extract_version_spec_class">EXTRACT_VERSION_SPEC</a>
 */
public interface ExtractVersionSpec {

  Boolean getIncludeAllVersions();

  Object getCommitTimeInterval();

  Boolean getIncludeRevisionHistory();

  Boolean getIncludeData();
}

It would be great to have a checkstyle rule that verifies that all classes in a project follow this convention.
