I added an instance variable to make this work in multi-tenancy

We should remember to update the documentation once this goes in so that users are aware of the instance parameter that needs to be added in the GH action.

Additionally, do we want to default instance to rapidapi.com? Just thinking that the self-serve users may not be aware of what instance means. If this is already how it works, my apologies.

@s-giovanni just added the change that should prevent existing integrations from breaking. Let me do another deeper dive before we merge though.
