refactor: Simplify tool listing in sentiment analysis test function

- Updated the `test_mcp_sentiment_analysis` function to streamline the output of available tools by using a single print statement with a join operation.
- This change enhances readability and reduces the number of lines in the code while maintaining the same functionality.
