@virajjasani Did you run Trino product tests with this PR?

[virajjasani]

@ebyhr please pardon my ignorance, but could you please point me to doc or instructions reg the local test setup required to do product test using local images? I tried building image with make testing/phoenix5.dependants. Now i need to test but not perform release steps as they would actually release the image to docker hub right?

I confirmed the product test result in my laptop.
