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.

• QUICKSTART-DEV.adoc: CONTRIBUTING.md -> .github/CONTRIBUTING.md

The quickstart points to it once more
The path is clear
The file is near
No wrong turn waits in store}
