Update number of mel bins for whisper model (#25675)
### Description
<!-- Describe your changes. -->
Update number of mel bins for whisper model as it differs based on the
Whisper model version. Otherwise I am unable to run Whisper v3 models as
the num_mel_bins is 128 for that.
### Motivation and Context
<!-- - Why is this change required? What problem does it solve?
- If it fixes an open issue, please link to the issue here. -->
Currently unable to run Whisper v3 models as the num_mel_bins is 128 and
it is fixed to 80 right now and causes issue during preprocessing.
