How do we avoid having a slightly different copy of RELEASING.md In every repo?

At the moment we would need:

• a script or action which automate the bump of the version in all package descriptors of a repo
• consider moving out the upgrade of the gemspec of the document by automating it
• or in the opposite document that process in all RELEASING.md
