Update pull request review enforcement of protected branch

Protected branches are available in public repositories with GitHub Free and GitHub Free for organizations, and in public and private repositories with GitHub Pro, GitHub Team, GitHub Enterprise Cloud, and GitHub Enterprise Server.

Note: The Protected Branches API now has a setting for requiring a specified number of approving pull request reviews before merging. This feature is currently available for developers to preview. See the blog post for full details. To access the API during the preview period, you must provide a custom media type in the Accept header:

application/vnd.github.luke-cage-preview+json

Warning: The API may change without advance notice during the preview period. Preview features are not supported for production use. If you experience any issues, contact your GitHub Enterprise site administrator.

Updating pull request review enforcement requires admin or owner permissions to the repository and branch protection to be enabled.
