Enhance streamUI to Include providerMetadata in Final Stream for Improved Access to Additional Information

[SalmanK81099]

This pull request introduces an enhancement to the streamUI function by including the providerMetadata in the final stream output. This change addresses the need for accessing additional information, such as citations in perplexity provider response, which were previously inaccessible.

Key Changes:

• Added providerMetadata to the final stream output of the streamUI function.
• This enhancement allows users to retrieve important metadata that can be crucial for various use cases, particularly in scenarios where detailed information is required for analysis or reporting.

Benefits:

• Improves the functionality of the streamUI by providing access to essential metadata.
• Facilitates better handling of complex scenarios where additional context is necessary for accurate processing and understanding of the model's output or for other purposes.
• This update aims to enhance the overall usability and flexibility of the streamUI function, ensuring that users have the necessary tools to work with the model's output effectively.

Why not set this to providerMetadata: ProviderMetadata instead of only supporting the perplexity metadata?
