Fix _patch_transformers_hybrid_cache also for peft

[albertvillanova]

Fix _patch_transformers_hybrid_cache also for peft:

• peft imported HybridCache from transformers.cache_utils
• it was fixed in peft v0.18.0: FIX: DynamicCache max_cache_len attribute error peft#2735

This PR updates the _patch_transformers_hybrid_cache function to improve compatibility with transformers v5 and ensure smoother integration with both liger_kernel and peft dependencies. The patch now checks for both packages' versions and updates documentation to reflect recent upstream fixes.

Dependency compatibility improvements:

• Updated the patch to check both liger_kernel and peft versions, ensuring compatibility with transformers v5 by applying the fix if either is below their respective fixed versions (liger_kernel<0.6.5 or peft<0.18.0).
• Enhanced the docstring to clarify that the patch addresses compatibility for both liger_kernel and peft, and that it can be removed once both dependencies are upgraded past their fixed versions.
• Improved the warning message to reference "transformers HybridCache compatibility" instead of just "liger_kernel", making the intent clearer when an exception occurs.
