local-gemma is not compatible with transformers 4.47

Installing the package using pip, by default installs the latest version of transformers (4.47).
Then, running the local-gemma command, returns the following error.

```
File "/local_gemma/attention.py", line 8, in
from transformers.models.gemma2.modeling_gemma2 import Gemma2RotaryEmbedding, apply_rotary_pos_emb, repeat_kv, GEMMA2_ATTENTION_CLASSES
ImportError: cannot import name 'GEMMA2_ATTENTION_CLASSES' from 'transformers.models.gemma2.modeling_gemma2'
(/transformers/models/gemma2/modeling_gemma2.py)
```

It turns out this has to do with a bug introduced in version 4.47.0 of the transformers package, in the file
'transformers/models/gemma2/modeling_gemma2.py'

Downgrading to version 4.46 solved the issue for me.
