Add check for dockerbuild

Description

This change is to ensure that anything that is pushed to any https://hub.docker.com/u/opensearchstaging is authored, reviewed and then pushed and build. Since the blast radius (even though in development) is high, we need to ensure the change is reviewed and has a source code.
