GH-52: feat(pipeline): Add table information to pipeline serialization

[Urfoex]

Adds a new Table data model and integrates it into the PipelineInformation model. This includes:

• A new serialization function serialize_tables to convert getML Tables objects.
• Updates to the main serialize_pipeline function to include table data.
• Corresponding additions to unit and integration tests to cover the new functionality.

Code Review

This pull request introduces serialization for table information within a pipeline. It adds a new Table data model, a serialize_tables function, and integrates this into the PipelineInformation model. The changes are well-structured and include corresponding updates to unit and integration tests. My main feedback is to add a None check in the new serialize_tables function for robustness, consistent with other serialization functions in the same file.
