Fixing timestamped-ASR with long audio recordings

[fabiocat93]

Description

Patch for fixing issues with timestamped-ASR with long audio recordings (same as here: huggingface/transformers#21262). In a related issue (huggingface/transformers#2615 (comment)), they recommended reducing the batch size and it seems to work from my tests.
