'POST' list calls incorrectly flagged with 'MISSING_RESOURCE_ID' and 'OBJECT_MISSING_REQUIRED_PROPERTY'

Here is an example: https://github.com/Azure/azure-rest-api-specs-pr/pull/13835/checks?check_run_id=15497000259

The method here is POST, in all 4 erroneous applications, the targeted operation is a custom POST action that should not have any requirment of returning an ID, and does not have 'id' in its schema. The linked schema in 'Missing_Resource_Id' is not the response schema for these operations.

Start by examining the linked check run and the Missing_Resource_Id validation rule, then trace how the response schema is selected for custom POST actions. Done means the four reported operations no longer receive MISSING_RESOURCE_ID or OBJECT_MISSING_REQUIRED_PROPERTY when their schemas omit id, with regression coverage for these cases if the repository provides it.
