[BUG]: the github_teams resource provides no way to retrieve child teams

[aiven-amartin]

Expected Behavior

https://registry.terraform.io/providers/integrations/github/latest/docs/data-sources/team or a similar resource should allow me to retrieve the child teams. For example, I want to retrieve the list of valid codeowners for a given repository. github_repository_teams only gives me the direct team members on the repository, and github_team only lets me retrieve the users on those teams, not their child teams. I need a resource that recurses the childTeams node in the graphql.

Actual Behavior

It doesn't

Terraform Version

github = {
  source  = "integrations/github"
  version = "~> 6.0"
}

Affected Resource(s)

• github_team
• github_repository_teams

I think that we can add support for this to the github_team data source using the REST API. I think we should also swap out the GraphQL implementation of the member lookup with the REST version.
