Not sure this is valuable yet, but leaving this option function as a starting
point for a future implementation. See https://github.com/palantir/policy-bot/issues/111
for some explanation of why this is desired.

In the Loader implementation, if a ClientCreator and InstallationsService are
set, the loadRemoteConfig method would use them to create a new client if the
remote owner does not equal the starting owner.

// WithPrivateRemotes enables loading remote configuration from private
// repositories in different organizations. By default, only public
// repositories can be remote targets.
func WithPrivateRemotes(cc githubapp.ClientCreator, installs githubapp.InstallationsService) Option {
	return func(ld *Loader) {}
