Unable to run Gemma-2-2b-it model using local TransformersModel

[NSTiwari]

I'm trying to use Gemma 2 2b-it model using TransformersModel via a local pipeline, but getting the following error:

Error in generating model output:
System role not supported

@aymeric-roucher Do you want me a utility function to covert system messages to user messages in util file? and pass a parameter to support these models? or if there is any other good approach let me know, I can patch it up
