The GitHub Rest API now has support for including the branches in a template repository using the include_all_branches parameter in the request; https://docs.github.com/en/rest/repos/repos#create-a-repository-using-a-template

I would like to request support be added to the github_repository resource to be able to specify this parameter when create a repository based off a template repository, so that the newly create repository has all the branches from the template instead of only the default branch.
