Upstream git repo has been moved

And https://tracker.debian.org/pkg/jackson-module-afterburner says

 package is gone
  This package is not part of any Debian distribution. Thus you won't
  find much information here. The package is either very new and hasn't
  appeared on mirrors yet, or it's an old package that eventually got
  removed. The old news are kept for historic purpose only.
