`ThreatIntelligenceIndicator_Get` - missing response properties

the response of [`ThreatIntelligenceIndicator_Get`](https://github.com/Azure/azure-rest-api-specs/blob/7245d0f5cc01bf95df9d7ae893f252d4001b4ad7/specification/securityinsights/resource-manager/Microsoft.SecurityInsights/stable/2022-11-01/ThreatIntelligence.json#L146) is defined as [`ThreatIntelligenceInformation`](https://github.com/Azure/azure-rest-api-specs/blob/main/specification/securityinsights/resource-manager/Microsoft.SecurityInsights/stable/2022-11-01/ThreatIntelligence.json#L470), but only contains little properties. We can't read the properties we set.

Start in specification/securityinsights/resource-manager/Microsoft.SecurityInsights/stable/2022-11-01/ThreatIntelligence.json and inspect the ThreatIntelligenceIndicator_Get operation alongside the ThreatIntelligenceInformation schema. Compare the response properties with the properties that can be set, then validate that the specification exposes those properties in the GET response.
