feat(aiplatform): add sample for Gen AI code model tuning (#3410)

* feat(aiplatform): add sample for Gen AI code model tuning

* udpate comments to make it clear

* fix: skip this test temporary until the service account permission issue is resolved

* fix: skip another pipeline test temporary until the service account permission issue is resolved

* fix(aiplatform): try to get the test to run after IAM role changed

* fix(aiplatform): remove the skip for another pipeline test

* fix: address review comments
