fix(profiling): forward GIT_REF + PR_NUMBER into Docker container

The previous commit moved these expressions from inline shell expansion
to job-level env: vars, but the profiling script runs inside a Docker
container. Job-level env vars are only visible in the runner, not inside
the container — they need explicit -e flags on the docker run command
(same pattern as HOST_GIT_COMMIT which was already forwarded).
