Added the Contributing.md and Code of Conduct File into the Repo

[ConnectBhawna]

I have added a Code of conduct along with Contributing guidelines to the project. In my Contributing guideline, I have not provided a link for the IHR Code of conduct, in case this gets merged I would add the link else the link would redirect to my repo. Let me know what you think about the rules and approach I have provided. @thunderbiscuit sir incase you need some changes let me know I would make and send the PR again.

Solved issue #245

Let me know if you're familiar with amending and force-pushing commits. In this case I'm looking for 1 commit, and I use the conventional commits convention including capitalizing the first word of the commit message and the active verb approach. For example your commit here would be:

Docs: Add CONTRIBUTING.md file

Okk @thunderbiscuit sir let me do this :)

Perfect thanks! Just two little things: I get notifications when people open issues or PRs on the repo, and when they comment on any of those. No need to tag me in all your messages 🤣. Also, you don't need to call me Sir.

Added the changes as you mentioned sir :)

I think you still have 3 commits, and incorrect commit messages. Let me know if you'd like help on how to fix this (see my message above).

You'll need to do an interactive rebase and force-push your new commit. In this case I'm looking for 1 commit, and your commit message will be:

Docs: Add CONTRIBUTING.md file
