Add data file with less known DC heroes for development testing

[Copilot]

Summary

Created a new data file less_unknow_heroes_data.json containing information about 6 less known DC superheroes for development testing purposes. This data will help with realistic testing of the application using characters that are not as famous as the main Justice League members.

Details

• Visited the official DC website (https://www.dc.com/) and navigated to the characters section
• Selected 6 less known superheroes:
  • Blue Beetle (Jaime Reyes)
  • Booster Gold
  • Rip Hunter
  • Atom Smasher
  • Doctor Fate
  • Cyclone
• Extracted relevant information for each hero:
  • Name
  • Alter ego
  • Powers
  • Team affiliation
  • Description
  • Image URL

Data Structure

The JSON file follows the same structure as the existing heroes_data.json file:

{
  "id": 1,
  "name": "Blue Beetle",
  "alterEgo": "Jaime Reyes",
  "powers": [
    "Alien Technology",
    "Durability",
    "Flight",
    "Super Strength",
    "Instant Weaponry",
    "Combat Skill"
  ],
  "team": "Teen Titans",
  "description": "The inheritor of a proud legacy of crimefighting...",
  "image": "https://www.dc.com/sites/default/files/styles/comics320x485/public/blue-beetle_192_0.jpg"
}

This data will help enrich the development environment with additional realistic superhero information.

Fixes #55.
