Remove `auto_map` from `config.json`

Jamba native support in Transformers was introduced upon https://github.com/huggingface/transformers/releases/tag/v4.40.0, so `auto_map` not required as it's pointing to remote code at https://huggingface.co/ai21labs/Jamba-v0.1 which can be a security risk as it requires the Transformers pipeline to add `trust_remote_code=True`
