I previously opened this PR before the TypeSpec migration and got it approved by ARM team: #33808
This PR is a continuation of that closed PR.

The Avocado error MISSING_APIS_IN_DEFAULT_TAG is a false positive. The API (/listclustercustomerusercredential) was previously deprecated and removed in 2022-10-27, which was already the default version before this PR.
ref: Azure/avocado#150

The RESPONSE_STATUS_CODE_NOT_IN_EXAMPLE error is intentional as the proxy update operation can only be performed on existing resources, while HTTP 201 is only returned when creating a new resource.
