Remove duplicate Javadoc block on sendExpandedToolResult()

modified: src/main/java/com/github/copilot/sdk/CopilotSession.java
- Remove the first of two identical Javadoc comment blocks that appeared
  in sequence above `sendExpandedToolResult()`. The method retains its
  single, correct Javadoc block describing the `ObjectNode` bypass for
  `session.tools.handlePendingToolCall`.
