🔨 refactor(prompts.py): swap suffix and format_instructions fields

🔨 refactor(util.py): add format_instructions to the list of fields to format in format_dict function
The suffix and format_instructions fields in the ZeroShotPromptNode class were swapped to improve the readability of the code. The format_instructions field is now above the suffix field, which makes more sense as it is a required field. In the util.py file, the format_instructions field was added to the list of fields to format in the format_dict function. This ensures that the format_instructions field is properly formatted when the function is called.
