Fix import for latest Transformers compatibility

- Updated `modeling_esm.py` to import `find_pruneable_heads_and_indices` from `transformers.utils.modeling_utils` instead of `transformers.modeling_utils`.
- Ensures compatibility with Transformers >=4.30.
- Enables AutoModelForSequenceClassification to load the model without ImportError.
