Add CODE OF CONDUCT file

[Pranjalll01]

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

could ypu please assign this to me ?
