arm64

[mathieu-benoit]

This PR has not yet perfectly tested the full arm64 support, but it's helping make progress towards this goal.

Here is what covers this PR:

• Took inspiration and learning from arm64 support mathieu-benoit/sail-sharp#162 for cartservice.

Here is what this PR is waiting for before going in an official "Ready for review" state from "Draft":

• Approval to run the CI tests against latest updates on this PR (arm64 #2589 (comment)) - This will guarantee that skaffold run still works and that the repo still works on the default amd64 platform/OS: https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/.github/workflows/ci-pr.yaml#L88C9-L88C21.

Here is what this PR is not covering and has not yet tested:

• scaffold dev from an arm64 platform/OS
• This doesn't publish the arm64 manifest entry for each container image published at each release of this repo - this needs more investigation. Something to change there https://github.com/GoogleCloudPlatform/microservices-demo/blob/main/docs/releasing/make-docker-images.sh#L43?
• kubectl apply -f on an arm64 Kubernetes cluster

Hi @mathieu-benoit ! What do you think is the effort needed to make this work?

From comments here it looks like there's still a ton of want for this feature: #622

@bourgeoisor and @NimJay, please could you approve the CI tests on this PR? I'd like to see what my latest changes will produce. Thanks!
