Fix Great Expectations v3 integration with airflow operator

[collado-mike]

Problem

main branch builds are failing due to integration test failures with the update to support Great Expectation's v3 API - see https://app.circleci.com/pipelines/github/OpenLineage/OpenLineage/2981/workflows/15bd0993-0423-4958-927d-a5d427993894/jobs/27943

Updated unit tests to catch the issue so that we can catch these in fork builds as well as main ones.

Note: All schema changes require discussion. Please link the issue for context.

@collado-mike I had earlier PR that also fixes the same thing. #688

Can we merge the test part of this PR?

Done. I kept the simplification in the _get_sql_table method, as I didn't see any point in having the same logic twice.
