Revert "KAFKA-16803: Change fork, update ShadowJavaPlugin to 8.1.7 (#…

…16295)" (#17218)

This reverts commit 391778b.

Unfortunately that commit re-introduced bug #15127 which prevented the publishing of kafka-clients
artifacts to remote maven. As that bug says:

    The issue triggers only with publishMavenJavaPublicationToMavenRepository due to signing.
    Generating signed asc files error out for shadowed release artifacts as the module name
    (clients) differs from the artifact name (kafka-clients).

    The fix is basically to explicitly define artifact of shadowJar to signing and publish plugin.
    project.shadow.component(mavenJava) previously outputs the name as client-<version>-all.jar
    though the classifier and archivesBaseName are already defined correctly in :clients and
    shadowJar construction.
