Add CONTRIBUTING.md file

[Pranjalll01]

Hey @Sakshamjain98
Pranjal here, Contributor @GSSOC'24
repository currently lacks a CONTRIBUTING.md file, which is an important resource for guiding potential contributors on how to engage with the project effectively. A CONTRIBUTING.md file outlines the contribution guidelines, coding standards, and procedures for submitting pull requests, thus streamlining the contribution process and ensuring consistency across contributions.
