Update get_random_sample_transcribe when absolute path is used in finetune_gradio.py

Update `get_random_sample_transcribe` to handle absolute paths in `finetune_gradio.py`

- Added support for processing absolute file paths during transcription.
- Updated logic to correctly handle and return audio file paths with absolute URLs.
- Example use case: URLs like `https://localhost:55555/speech/150/150896/150-150896-40.wav.wav`.
- Correct one should be: `https://localhost:55555/speech/150/150896/150-150896-40.wav`.
