Handle sample_data failure on run_local_docker.sh

[pmbrull]

Affected module
CI tests

Describe the bug
When there are changes impacting the correct behavior of the sample data ingestion, we are currently not picking up any errors. Instead, we let the py-tests CI pipeline timeout, which can be ignored during merging.

To Reproduce

Screenshots or steps to reproduce

Expected behavior
We should properly raise an explicit fail during run_local_docker.sh when this happens. It might be tricky as the pipeline runs automatically in the ingestion container, but we might be able to ping the pipeline status.

Version:

• OS: [e.g. iOS]
• Python version:
• OpenMetadata version: [e.g. 0.8]
• OpenMetadata Ingestion package version: [e.g. openmetadata-ingestion[docker]==XYZ]
