When users try to publish to a GitHub organization but don't have
permission, the error message now includes a helpful hint suggesting
they may need to make their organization membership public in GitHub
settings.
This addresses the issue where users couldn't understand why they were
unable to publish servers from organization repositories, even when they
were members of the organization.
Fixes#398
