Thank you for your contributions - changes I am requesting are hopefully obvious/straightforward...

also please be aware - depending on which notebooks-v1 workflow PR is ready to merge first - we may also need a rebase as some of the testing/gh-actions files are also being created in additional PRs being raised.

Thanks for your continued engagement.. getting closer to having something merge-able.. but still need to do a little more refining.

Please reach out to me if you need/want more details about how you can test this on your fork to gain confidence in its functionality on the upstream repo.

Thanks again for your continued attention to this PR... just a couple more things to clear up..

• please ensure the DCO checks on your PR are passing.. you can probably squash some/all of your commits if you want to avoid having to make sure each one is signed
• fix up the indenting that was introduced (i'm guessing unintentionally) to kind-1-25.yaml

Looks like you introduced an indentation here that was not present in the source originally:

• https://github.com/kubeflow/kubeflow/blob/master/components/testing/gh-actions/kind-1-25.yaml#L4-L7

Preserving original formatting will avoid a merge conflict if/as some other PR that includes this file gets merged first.
