With the addition of github_repository it may be confusing that
github_team_repository only creates relationships, rather than creating
actual repositories. To reduce the chance of confusion, we'll make this
explicit in the docs for github_team_repository.
Also taking this opportunity to make the examples consistent with what
would be produced by hclfmt.
GitHub really doesn't like when you make the H lowercase, it violates
their brand guidelines and they won't help promote anything that doesn't
use the capital H.
