Added ccpemv2.jsonl file

A modified dataset consisting of 12,000 records of English dialogs between a user and an assistant discussing movie preferences in natural language. In the foundational dataset, it initially had 502 records. To enhance the dataset's scope, I expanded it to include a total of 12,000 records.
