[yanchai2025]

Motivation

This pull request introduces a new pattern builder for masking JSON bodies, updates the documentation to reflect the available pattern builders, and adds comprehensive tests for the new functionality. The main goal is to enhance support for masking sensitive data in JSON objects by providing a dedicated builder and ensuring its correctness.

• Added JsonBodyPatternBuilder class to provide regex-based masking for JSON bodies, supporting cases like masking entire nested objects (e.g., credit card numbers).
• Updated the README.md to include links to all available pattern builders, including the new JsonBodyPatternBuilder and others, with direct references to their source files.

Test Plan

Added JsonBodyPatternBuilderTest to do the test.
