Make audio for transcribed segment playable by integraing play button next to the segment

[menelic]

this has been implemented here https://github.com/hayabhay/whisper-ui in combination with your confidence color coding this would be a very useful feature

still from this short video: https://user-images.githubusercontent.com/6735526/216852681-53b6c3db-3e74-4c86-806f-6f6774a9003a.mp4

alternatively, create a display mode that makes transcript snippets playable just by clicking on them, as in the amberskript interface
