Review comment (suggestion):
This parameter appears to be mandatory, not optional, here.

https://developer.github.com/v3/repos/branches/#update-branch-protection lists `required_approving_review_count` in a table labeled as:

> The `required_pull_request_reviews` object **must** have the following keys

Emphasis on _must_.

So, it should be:

```Go
RequiredApprovingReviewCount int `json:"required_approving_review_count"`
```
