Tested on my end. Everything works.
May be a nit: Since --vector-dim assumes default of 1536, I think we should update README.md for Step 3: Run the benchmark that the cli argument needs to be used when running search phase else it raises MilvusException: vector dimension mismatch.

Thanks @idevasena for trying out the PR. Updated README.md with --vector-dim parameter use.
Working with mlcommons support team to get me added to approved contributors list.
