Describe the bug
githubrepo.Client.GetOrgRepoClient() simply calls CreateGithubRepoClient(). Instead it should call CreateGithubRepoClientWithTransport() and pass in its own client's transport client.repoClient.Client().Transport.

Reproduction steps
Have an authenticated transport, say it

rc := githubrepo.CreateGithubRepoClientWithTransport(ctx, it)
res, err := scorecard.Run(ctx, repo,
	scorecard.WithRepoClient(rc),
	scorecard.WithChecks([]string{"Security-Policy"}),
)

This should work, but you get:

ERRO[0001] GitHub token env var is not set. Please read https://github.com/ossf/scorecard#authentication  error="an error occurred while getting GitHub credentials"

due to: https://github.com/ossf/scorecard/blob/main/checks/raw/security_policy.go#L63

Expected behavior
Auth works.
