Update info.json for RPG cog metadata clarity

Enhanced the metadata in `info.json` for the RPG cog by updating the install message, short description, and adding a detailed description of its functionality. Simplified requirements and permissions fields, expanded tags for better discoverability, adjusted the min Python version format, and clarified the end user data statement for transparency.
