Add counting sort in the list of sorting techniques

[kratik1237]

Description
We need to add Counting Sort to our existing list of sorting techniques in our documentation/codebase. Counting Sort is a non-comparison-based sorting algorithm that sorts elements in linear time complexity for a specific range of input.

Use Case

• Enhances our sorting algorithm collection
• Provides an efficient sorting method for integers or objects with integer keys
• Useful for educational purposes to demonstrate different sorting paradigms
• Can significantly improve performance in scenarios with a limited range of input values
