Pro Subscription must be public to get recognized

[herrfugbaum]

If the sponsorship visibility is set to private, ScriptKit does not recognize that there is a paid subscription.

It is probably a good idea to give a hint to users that the sponsorship needs to be set to public to work.

@herrfugbaum Oh, thanks for pointing that out!

I'll adjust the API to include the private sponsors as well. It was a setting in GitHub graphql API I wasn't aware of.
