Subscription schema is missing from latest versions and the only one available is outdated

I need the `/subscriptions/{subscriptionID}` path output schema for the 2020-01-01 or newer package version

I could only find it here: https://github.com/Azure/azure-rest-api-specs/blob/main/specification/subscription/resource-manager/Microsoft.Subscription/stable/2016-06-01/subscriptions.json#L210-L253

But the 2016-06-01 package is outdated schema, missing the `tenantId` field which was added later

I cannot find the same thing here https://raw.githubusercontent.com/Azure/azure-rest-api-specs/main/specification/subscription/resource-manager/Microsoft.Subscription/stable/2020-01-01/subscriptions.json

Or any other version

Compare the schema in specification/subscription/resource-manager/Microsoft.Subscription/stable/2016-06-01/subscriptions.json with the 2020-01-01 subscriptions.json referenced in the issue. Start at the `/subscriptions/{subscriptionID}` path and verify the newer package exposes the output schema, including `tenantId`; done means the 2020-01-01-or-newer schema is present and reflects the later field.
