Summary of Changes

Hello @aIbrahiim, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses and fixes a flaky pre-commit test related to the Java Kafka IO Direct component. The solution involves enhancing the schema definition for Kafka read configurations by explicitly assigning field numbers to key properties. This ensures a consistent and stable schema, which in turn resolves the intermittent test failures that were occurring due to an unstable schema structure. The corresponding test suite has been updated to validate these new schema definitions.

Highlights

• Schema Field Numbering: Added explicit @SchemaFieldNumber annotations to several configuration fields within KafkaReadSchemaTransformConfiguration.java to ensure stable field ordering and identification.
• Test Updates: Updated KafkaReadSchemaTransformProviderTest.java to reflect the increased schema field count and include new assertions for the newly numbered fields, verifying their correct definition.
• Flaky Test Fix: Resolved a pre-commit Java Kafka IO Direct flaky issue by stabilizing the schema definition, which was likely the root cause of the intermittent test failures.
