Use docker cp instead of a bind mount to get repo files into the playwright container

This script runs inside the runner's own job container and talks to the
host's docker daemon over a mounted socket (docker-outside-of-docker). A
bind mount path only exists inside this job container, not on the host the
daemon resolves it against, so docker run -v failed with ENOENT. docker cp
copies file contents instead, sidestepping the path mismatch.
