The E2E action intermittently fails building the aiperf-bench image:

  #5 [2/3] RUN pip install --no-cache-dir "aiperf==0.7.0" ...
  #5 0.183 runc run failed: unable to start container process: error during container init:
    exec: "/bin/sh": stat /bin/sh: no such file or directory

Root cause

The docker build in .github/actions/e2e/action.yml:104 lacks an explicit --platform flag.
Without it, Docker BuildKit may resolve the wrong architecture manifest for the python:3.12-slim multi-arch image, producing a layer tree where /bin/sh doesn't exist for the host architecture.

Why only aiperf-bench is affected:

• Go validator images (deployment, performance, conformance) are COPY-only into distroless — no RUN steps, so /bin/sh is never invoked
• Release workflows (on-push.yaml, on-tag.yaml) use docker/build-push-action with explicit platforms: matrix values

Fix

Add --platform linux/amd64 to the E2E docker build for aiperf-bench.
