This is a special repository that allows proliferating a few different supported file types such as a PR template and an issue template.
For example, since there is a .github/PULL_REQUEST_TEMPLATE.md in this repo, then if there is a repo that does not have this file, that repo will use the default PR template defined in this repo.
