[Question] How to define so that an API is only available on a Self Hosted Gateway (and not on 'Managed') ?

### Release version

APIOps Toolkit for Azure APIM v6.0.1.3

### Question Details

How can I define that an API should only be available on a Self Hosted Gateway and not on 'Managed' ?
In the AZure Portal API Management UI this is done by removing 'Managed' in the gateways property.

### Expected behavior

I would like to have the possibilty to 'deny' availability on 'Managed'

### Actual behavior

When a new API is created via APIOps, 'Managed' is always included in the 'gateways' property in the 'Azure Portal API Management UI' API Settings

### Reproduction Steps

1. Create an API in the 'Azure Portal API Management UI'
2. Remove 'Managed' from the 'gateways' property in the 'Azure Portal API Management UI' (API > Settings tab)
3. Extract the API Management configuration with the 'extractor' tool
4. Delete the API in the 'Azure Portal API Management UI'
5. Publish the extracted API Management configuration from Step 3
6. Check the 'gateways' property in the 'Azure Portal API Management UI' (API > Settings tab), it will have 'Managed' which is not wanted

Inizia con lo strumento extractor e confronta la configurazione API estratta con la proprietà gateways dell’API dopo la pubblicazione. Traccia come vengono lette e applicate le assegnazioni dei gateway, quindi verifica che un’API estratta senza Managed rimanga non disponibile su Managed dopo essere stata ripubblicata.
