Add New Prompt

You'll need to add your prompt into README.md, and to the prompts.csv file. If your prompt includes quotes, you will need to double-quote them to escape in CSV file.

If the prompt is generated by AI, please add <mark>Generated by AI</mark> to the end of the contribution line.

• [X ] I've confirmed the prompt works well
• [ X] I've added Contributed by: [@yourusername](https://github.com/yourusername)
• [X ] I've added to the README.md
• [ X] I've added to the prompts.csv
  • [X ] Escaped quotes by double-quoting them
  • [ X] No spaces after commas after double quotes. e.g. "Hello","hi", not "Hello", "hi"
  • [ X] Removed "Act as" from the title on CSV

Please make sure you've completed all the checklist.

Not sure why am getting Error: CSV headers must be exactly [act, prompt] this error. Followed exact spacing and structure as others.
