[DOCS] Fix incorrect model name in conversation management example

[aws-banjo]

Description

Fixed incorrect model name in conversation management documentation example. Updated claude-haiku-4-20250514 (which doesn't exist) to the correct claude-3-5-haiku-20241022 model name in the SummarizingConversationManager example.

Type of Change

• Bug fix
• Typo/formatting fix

Motivation and Context

The documentation contained an example using a non-existent model name claude-haiku-4-20250514. This would cause errors for users trying to follow the example code. The correct model name is claude-3-5-haiku-20241022, which is the actual Claude 3.5 Haiku model available from Anthropic. View full list here
