Pull Request Overview

This PR adds error code cause chain tracking to connection failure telemetry events. The change enhances error reporting by capturing error codes from the entire cause chain of connection failures, which is particularly useful for debugging issues with the MongoDB driver and OIDC library that utilize error cause chains.

• Adds error_code_cause_chain field to the ConnectionFailedEvent telemetry type
• Implements getErrorCodeCauseChain utility function to extract error codes from cause chains
• Integrates the new error code cause chain data into connection failure tracking
