MINOR: Enhance Sample Data with Owner and Descriptions (#22872)

* Enhance Sample Data Generation: Update table and column limits, add description and owner fields to table creation requests in sample_data.py

* Refactor SampleDataSource: Improve readability by adjusting conditional formatting for owner checks in sample_data.py

* Reduced number of tables per schema to 10

* Update sample_data.py: Reduce the maximum number of columns per table from 2000 to 200 for improved data generation efficiency
