Correct long-form generation config parameters 'max_initial_timestamp_index' and 'prev_sot_token_id'.

Hey Subhaka 👋,

Your model repository seems to contain outdated generation config parameters, such as 'max_initial_timestamp_index' and is missing the 'prev_sot_token_id' parameter. These parameters need to be updated to correctly handle long-form generation as stated in as part of https://github.com/huggingface/transformers/pull/27658. This PR makes sure that everything is up to date and can be safely merged.

Best, the Transformers team.
