DCO tests in GitHub Actions ensure code contributions are legally sound. We are implementing stricter DCO checks. Currently, DCO compliance is not enforced as a pre-merge requirement.

Sample PR where DCO passes : https://github.com/databricks/databricks-sql-python/pull/461/commits.

But, sadly the sign-off should be part of every commit message for DCO GH action to pass. The idea is to make it more developer friendly.
