fix(docs): repoint references to the relocated contributing guide

The guide moved to .github/CONTRIBUTING.md; these references still resolved
against the old root location and 404 from where they are written. Rewritten
using the correct relative depth.

• .github/CONTRIBUTING.md: in-guide links withdrawn one level to the root
• examples/newsroom/README.adoc: ../CONTRIBUTING.md -> ../../.github/CONTRIBUTING.md
• playground/SECURITY.adoc: CONTRIBUTING.md -> ../.github/CONTRIBUTING.md
