Is your feature request related to a problem? Please describe.

The grpc and http example passthrough servers have images pushed to public repos (quay.io/solo-io/passthrough-grpc-service-example, gcr.io/solo-public/passthrough-http-service-example).

These images have architecture issues in certain contexts:

• In EKS with existing image
• In GCloud with updated locally built images (build on an M1 mac) - this works with the existing which also has an arm architecture

Additionally, a recent PR added additional debugging options, so it would be good to get new images published with that functionality.

Describe the solution you'd like

Images that are validated to work in all necessary environments

Describe alternatives you've considered

No response

Additional Context

The existing images are old and very infrequently updated. There is no pipeline/git action, and developers are able to push new images for these repos from their dev environments if they are logged into quay/gcr.
