Submitter Checklist

• [ ] ♽ Run make test lint before submitting a PR (ie: with pre-commit, no need to waste CPU cycle on CI
• [ ] 📖 If you are adding a user facing feature or make a change of the behavior, please verify that you have documented it
• [ ] 🧪 100% coverage is not a target but most of the time we would rather have a unit test if you make a code change.
• [ ] 🎁 If that's something that is possible to do please ensure to check if we can add a e2e test.
• [ ] 🔎 If there is a flakiness in the CI tests then don't necessary ignore it, better get the flakyness fixed before merging or if that's not possible there is a good reason to bypass it. (token rate limitation may be a good reason to skip).

@chmouel @sm43 would you please review this PR. Currently in my testing, it took only ~20min to build amd64/ppc64le/s390x multi-arch images compared to old builds with ~1Hr. Build details: https://github.com/Basavaraju-G/pipelines-as-code/actions

would it okay if we run this as nightly(once a day) rather than after each pr merge?

@sm43 I agree with you for nightly build. but i see for every PR we are running only "E2E Tests on kind". we are not running "Create and publish a Docker image" workflow. this changes only works on building image time. not for every PR.

yeah I meant for every merged PR. whenever a new PR is merged this is triggered

we were wondering if using ko can help us with this 🤔 https://github.com/marketplace/actions/setup-ko for multi platform images I need to try this out.

[sm43]

Can you add a new workflow with this changes running nightly? later if ko works as expected we can replace
