Data Ingestion Makefile setup and execution

[dan-hansen]

When I setup a new project using the adk rag option with Vector Search the "make data-ingestion" command failed for a couple of reasons. Sharing my resolution in case there is an issue with the setup or something I did differently.

1. I failed due to access to the service account and realized in the error message it was expecting "my-project-rag" whereas my service account was named for my actual project name. It seems in the Makefile that a parameter replacement for "my-project" is missing. When I replaced the value, the make command worked fine.
2. The pipeline failed at step 3 with a 400 invalid parameter error. It turned out I needed to give the explict resource path in the Makefile for data-ingestion parameters vector-search-index and vector-search-index-endpoint.

Thanks a lot @dan-hansen - will look at it and see if the code needs editing!
