• Add Code Climate Badge (maintainability)
• Add Code Climate Badge (code coverage)

So, maintainability and code coverage isn't available for C code in code climate as of Oct-14-2023. But there exists a plugin for C that describes code complexity called GNU Complexity

Added Badges but seeing how I can add other plugins, specifically:

• Gnu Complexity
• cppcheck
