GH-743: Skip the apache-release source-release zip

Release CI unpacks JNI tarballs into the working tree before Maven runs,
so the parent's source-release assembly would package those binaries
(hundreds of MB). Set skipAssembly on the root source-release-assembly
execution (same pattern as bom/pom.xml) and drop the forked descriptor.
The artifact we vote on and publish remains the git-archive tarball.

Closes #743.
