Description

Replace Transform currently supports replacing a single field through replace_field.
To support multiple target fields in one transform, this change expands the configuration to replace_fields and treats it as List<String>.

For backward compatibility, the legacy replace_field key is still supported.

Goals

• Add new unit tests for Replace Transform where unit test coverage did not previously exist
• Add E2E tests for Replace Transform changes
• Convert replace_fields to List<String>
• Keep backward compatibility with legacy replace_field
• Support replacing multiple fields in a single Replace Transform
• Update Replace Transform documentation to use replace_fields as the primary key
• Add a compatibility note in the documentation for legacy replace_field
