Code Review

This pull request updates the BigQuery generated models to include several new fields (such as rows, copy, extract, format_options, job_type, kind, and load) and updates the type of job_timeout_ms to wkt::Int64Value. Additionally, it refactors the package descriptions, metadata, and documentation for various Shopping Merchant API sub-crates to use more specific names. I have no feedback to provide as there are no review comments.

these BigQuery generated files should not be changing, need to merge #6277 first to add the list of fields to be skipped on code generation.
