Fixes issue from #9150 . As its a one-line fix, merge should be fairly simple

Code Review

This pull request correctly fixes the path for the openroad binary in the multi-stage Docker build. The change in the Dockerfile updates the COPY instruction to point to /OpenROAD/build/bin/openroad, which aligns with the RUNTIME_OUTPUT_DIRECTORY specified in the CMake configuration. This is a necessary and accurate one-line fix to ensure the Docker image is built with the correct binary.

The DCO failing check is related to me not cryptographically signing the commit for this one-liner
