PR Overview

This PR introduces pluralization functionality for Rosetta by adding new operator classes, corresponding tests, and integrating pluralization rules into the model and schema.

• Added operator classes (LessThan, LessThanOrEqualTo, EqualTo, GreaterThan, GreaterThanOrEqualTo) with a common BaseOperator interface
• Introduced tests for each operator and updated the PluralizationRule model, migrations, and fixtures accordingly
