Script to add all organization repos to a team

It would be useful to have a script that:
1. Gets a list of organization-owned repos
2. Adds all of those repos to a specified team

Alternatively, it might be better to allow the user to specify a list of repos instead, passing it to the command.

Start by locating the existing script or command structure for organization and team operations; the issue does not name a file or entry point. Decide whether the input should be all organization-owned repositories or an explicit repository list, then verify that the chosen mode adds every requested repository to the specified team.
