Include All Branches in template repositories (#1353)

* Include All Branches in template repositories

When creating a repository from a template, you can pass in a boolean to
include all the branches in the template repo.

This is documented here: https://docs.github.com/en/repositories/creating-and-managing-repositories/creating-a-repository-from-a-template

In addition, the provider already supports that here: https://github.com/google/go-github/blob/3e8a7f0fbe0e4402f9ad5a80e0ab0a050786e0f8/github/repos.go#L441

Adding a variable under the template structure and then pass it in to
the provider function works.

Added tests to make sure it works. All tests are passing

* Remove failing test. Nothing to see here, folks

* Add clarifying doc note
