### Please describe the feature.

Hello, inquiring to see if adding support for `Self Contained Interactive Authoring` (boolean) when creating a Synapse Self Hosted Integration Runtime (SHIR) is on the roadmap or not?

This should be similar to the Data Factory support of this option.

[API Spec](https://github.com/Azure/azure-rest-api-specs/blob/main/specification/datafactory/resource-manager/Microsoft.DataFactory/stable/2018-06-01/entityTypes/IntegrationRuntime.json#L645)

[API Docs](https://learn.microsoft.com/en-us/rest/api/datafactory/integration-runtimes/create-or-update?view=rest-datafactory-2018-06-01&tabs=HTTP#selfhostedintegrationruntime)

Start with the linked Synapse integrationRuntime.json API specification and compare its Self Hosted Integration Runtime definition with the linked Data Factory IntegrationRuntime.json reference. Confirm the requested boolean's schema and placement; done means the Synapse API specification exposes Self Contained Interactive Authoring consistently with the ADF reference.
