The `AzureStorageInfoValue.endpoint` property is not exposed in the rest api spec, however when trying to mount a file share, the property is required. Otherwise the service will return

{"ErrorEntity":{"ExtendedCode":"01033","MessageTemplate":"Theparameter '{0}' has an invalid value. Details:{1}.","Parameters":["Endpoint","Endpoint cannot be empty for File Sharestorage mounts"],"Code":"BadRequest","Message":"The parameter 'Endpoint'has an invalid value. Details: Endpoint cannot be empty for File Sharestorage mounts."}}],"Innererror":null}
```

### Expected behavior

### Actual behavior

The property is not listed in the swagger

### Reproduction Steps

N/A

### Environment

_No response_

Start with the linked 2025-05-01 openapi.json at line 43308 and inspect the AzureStorageInfoValue schema. Confirm how the endpoint property is represented in the source specification, then verify that the completed schema exposes it for file share mounts.
