This is a quick fix for issue huggingface#40874. The `T5GemmaConfig` class was missing the `num_hidden_layers` attribute that cache initialization expects. Added `attribute_map` and `num_layers` property following the same pattern used by `T5Config` to expose the decoder's `num_hidden_layers` value.

forgot that it was an encoder decoder hahah there might be a better way to fix this @gante I don't remember what we do in that case
This is a quick fix for issue huggingface#40874. The `T5GemmaConfig.get_text_config()` method was always returning self instead of the appropriate sub-configuration. This caused cache initialization failures because the main config lacks `num_hidden_layers` while the decoder/encoder sub-configs have this attribute. Now the method correctly returns the decoder config when `decoder=True` and encoder config when `encoder=True`, allowing `cache_utils.py` to obtain the proper configuration with `num_hidden_layers` for cache initialization.

uhmmm this is not wanted, it means config.get_text_config is not fetching the decoder for this model correctly. Having a look at the original issue
