GitHub Docs

[RehanSaeed]

@krajek I added every type of GitHub document under the .github folder. Been going through all my repos doing so.

One of the docs is funding.yml which adds a sponsor button to the top. Never tried it, don't expect anything from it but am giving it a go. I added you as a GitHub user but you need to register for the GitHub sponsors beta. I also registered you for the Open Collective project, you should have received an email. Feel free to add your other details.
