chore: update examples to work with podman on macos

[YOU54F]

Testing out the examples on MacOS with Podman, over Docker compose

brew install podman
podman machine init
podman machine start
export DOCKER_HOST='unix:///Users/yousaf.nabi/.local/share/containers/podman/machine/qemu/podman.sock'
make examples

Notes

• Unable to bind to ports <1024
  • Updated to 9292 and updated all examples and unit test to reflect
  • Can be used with podman machine --allow-rootful
• Links in docker-compose.yml not valid
• host.docker.internal workaround not required
• nginx config isn't used in tests, can be commented out from docker-compose.yml and all examples pass
• target_platform check is still required, need consideration for how to support both podman and docker users on MacOS.
