Hello Team,

I am trying to run https://github.com/aws-samples/amazon-bedrock-workshop/blob/main/03_QuestionAnswering/01_qa_w_rag_claude.ipynb but its throwing a null exception with the following stacktrace

    response = self.client.invoke_model(
AttributeError: 'Bedrock' object has no attribute 'invoke_model'

During handling of the above exception, another exception occurred:

Please retest with latest version of repo and latest SDK now that Amazon Bedrock is Generally Available. The dependencies are no longer required and SDK has now two clients, bedrock and bedrock-runtime. Workshop has been updated accordingly.
