Move away from Google Container registry, and cloud build system for image builds

[HumairAK]

As per the last KFP call on 2024-09-11

It was decided that the following pieces that are part of the release process are still highly dependent on google infra:

• Buildling mechanism, currently we’re using cloud build mechanism
• container registry, technically you can use the github container registry, but not sure if there’s a ratelimiting

Suggestion:

This looks like we can easily resolve this dependency by utilizing Github Actions as the build mechanism, and using Github Container Registry. With KF as a CNCF project we should have enterprise access to GitHub Container Registry.

cc @chensun / @zijianjoy I've added a PR for a workflow that will build and push images to the kubeflow/pipelines github container registry

how does this sound to you? based on their pricing it seems it's free for public repos: https://github.com/pricing

If there's anything missing that we need from enterprise, we can reach out to CNCF for enterprise access (however that works)
