The failing aks test is still running on dev branch.

@binbin-li Thanks for looking into this. Can we actually just remove the Update Az cli step. The original reason we had added this was to force upgrade the runner to new az cli version which had a bug fix. It seems that GH runner images now use a newer version. https://github.com/actions/runner-images?tab=readme-ov-file#available-images

Binbin, wondering if you are able to apply the safe to test label to trigger the aks test?
