Describe the bug

When I try to use NeMo Guardrails with Amazon Bedrock I face a issue with message

ValidationException: An error occurred (ValidationException) when calling the InvokeModel operation: Malformed input request: #: extraneous key [max_tokens] is not permitted#: extraneous key [n] is not permitted, please reformat your input and try again.

Checking the code, I perceived a hard coded max_tokens: 10 parameter for kwargs.

Steps To Reproduce

Configure a rail using Amazon Bedrock

Expected Behavior

NeMo Guardrails answer with LLM response

Actual Behavior

A error occurs:

ValidationException: An error occurred (ValidationException) when calling the InvokeModel operation: Malformed input request: #: extraneous key [max_tokens] is not permitted#: extraneous key [n] is not permitted, please reformat your input and try again.
