fix(tests): remove redundant integration test wf

[droctothorpe]

Description of your changes:
Identical sample tests are being run in two separate CI workflows for some reason: kfp-samples and kubeflow-pipelines-integration-v2. The first invokes sample_test.py. The second does as well (after pathing through a Makefile). Presumably, we don’t need both.

I suggest we tackle eliminating integration-test.sh and some of the corresponding out of date docs in a follow-up PR. There should be one, clearly documented path for running large tests both in CI and from local.

Just to share a bit history, in the past, sample tests and integration tests are different workflows, IIRC, the former runs against the latest release--we do this by maintaining a long running deployment and update it post every release--while the latter runs against the built from master head + the PR being tested--developing on the fly.
I sense this current GA workflow may have merged, but in the long run, I think there're value to test with both stable (release) and branch head.
