Move kubeflow-pipelines-samples-v2 to GitHub Actions

[hbelmiro]

As part of #10744, we need to migrate kubeflow-pipelines-samples-v2 to GH Actions.

The output of this issue is:

• The new GitHub workflow created and passing
• The existing Prow configuration removed from https://github.com/GoogleCloudPlatform/oss-test-infra/blob/master/prow/prowjobs/kubeflow/pipelines/kubeflow-pipelines-presubmits.yaml

You can use the following PRs as a reference:

• test: Moved kfp-kubernetes-execution-tests to GitHub Actions #10926
• chore: Remove KFP presubmit kubeflow-pipeline-e2e-test test prow config GoogleCloudPlatform/oss-test-infra#2298
