• Update M2E's contribution to the Eclipse Simultaneous Release:
  https://git.eclipse.org/c/simrel/org.eclipse.simrel.build.git/tree/m2e.aggrcon, usually it is sufficient to update the repo URL and description.

  In the Review Documentation section add the New & Notworthy URL:
  https://github.com/eclipse-m2e/m2e-core/blob/master/RELEASE_NOTES.md#<M2E_RELEASE_WO_DOTS>
