Support for Initial Prompt and Hotwords in WhisperPipeline (similar to faster-whisper)

[HighBridgeDragon]

Hello OpenVINO team,

I'm currently using the WhisperPipeline in openvino.genai and would like to request a feature similar to that of faster-whisper (CTranslate2), where users can provide an initial_prompt or specify hotwords to influence the transcription process.

This feature would be particularly useful in cases where we want to improve transcription accuracy for specific terms or in domain-specific contexts.

Feature Request:

• Add support for initial_prompt in the WhisperPipeline.
• Add support for hotwords or custom vocabulary injection, allowing users to specify words/phrases that are prioritized during transcription.

Is there any existing workaround or plan to incorporate these features in openvino.genai?

Thank you for considering this feature request!
