flake: verify_examples zipkin-tracing

[kyessenov]

Noticed this a couple of times today:

TESTS FAILED:
run_examples@ /home/vsts/work/1/s/ci/verify_examples.sh :39 (./zipkin-tracing)
  > main@ /home/vsts/work/1/s/ci/verify_examples.sh :44

almost certainly this is a dupe of https://github.com/envoyproxy/envoy/issues/22404

upstream issue is here https://github.com/docker/hub-feedback/issues/2262

checking CI im not seeing the docker issue - so this may be genuine separate flake - ill look further
