Duo Workflow in CI should push code to the branch we created

Related to !176742 (comment 2322561632) . At present the code changes made in workflow run in CI are just lost.

We considered uploading them all as artifacts but this seemed pointless for now as our main goal is to have it push code up to a branch.

I tried with the code in !176742 (merged) and there are still some challenges with pushing code. Right now it thinks that it is in a detached head state. We need it to know about the branch we created for it. And we also need it to have valid git credentials that can push code.
