Pydantic V2 fails to parse ingestion source

[remisalmon]

Describe the bug

Pydantic V2 that is installed as a dependency of the acryl-datahub pip package fails to a file base lineage ingestion source.

To Reproduce
Steps to reproduce the behavior:

1. Install acryl-datahub==0.15.0.1 in a new python venv
2. Create a datahub-lineage-file ingestion source: https://datahubproject.io/docs/generated/ingestion/sources/file-based-lineage/
3. Run datahub ingest --config <ingestion source above>.yml
4. Ingestion fails with ERROR {datahub.ingestion.run.pipeline:537} - Ingestion pipeline threw an uncaught exception: 757 validation errors for LineageConfig

(the 757 is an example)

Expected behavior

The ingestion does not fail.

A workaround is to force pydantic>=1,<2 in the pip requirements.
