🚀 feat(test_prompts_template.py): change type of "suffix" and "prefix" fields to "prompt" and update "format_instructions" field

The "suffix" and "prefix" fields have been changed from type "str" to "prompt" to allow for more flexibility in the input. The "format_instructions" field has been updated to be required and multiline, and to show the instructions by default. This change will make it easier for users to understand the expected input format.
