Add GitHub Projects Task Generator Prompt

Added a new prompt for generating structured task lists from project specifications in Markdown format. This prompt helps users convert detailed requirements into clear, actionable checklists suitable for GitHub Projects.

Changes Made

• Added "GitHub Projects Task Generator" prompt to README.md following the established format
• Added corresponding entry to prompts.csv with proper escaping and formatting
• Set for_devs flag to TRUE since this is a developer-focused tool
• Ensured the prompt covers all aspects of task generation including:
  • Breaking down specifications into organized tasks and subtasks
  • Following the - [ ] Task title Markdown checkbox format
  • Combining or generalizing repetitive tasks while keeping clarity
  • Producing only a clean Markdown output without explanations or code blocks
  • Ensuring tasks cover functionality, validation, security, interface, and quality

Checklist

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

This prompt helps project teams streamline their workflow by automatically transforming complex project specifications into structured, ready-to-use GitHub task lists.
