Add CONTRIBUTING.md

[Dhanwantisatone]

Description:
The repository currently does not include a CONTRIBUTING.md file. Adding one would provide clear guidelines for new contributors on setting up the project, following coding standards, and submitting pull requests.

Proposed Solution:

• Add a CONTRIBUTING.md file in the root directory.
• Include sections on project setup, branch/commit conventions, and PR process.

Benefits:

• Improves clarity for contributors.
• Encourages consistent contributions.
• Makes the project more beginner-friendly.

Suggested Labels:
good first issue, hacktoberfest, hacktoberfest-accepted
