Doesn't recognize 2021-12-01-preview for Microsoft.ApiManagement/service/apis

[StephenWeatherford]

This is straight from the unit tests:

{
    "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
    "contentVersion": "1.0.0.0",
    "resources": [
        {
            "type": "Microsoft.ApiManagement/service/apis",
            "apiVersion": "2021-12-01-preview",
            "name": "foo/bar",
            "properties": {
                "displayName": "test",
                "apiRevision": "1",
                "description": "Init",
                "subscriptionRequired": true,
                "path": "foo",
                "protocols": [
                    "https"
                ],
                "isCurrent": true,
                "apiVersion": "v1", // this should not be flagged
                "apiVersionSetId": "[resourceId('Microsoft.ApiManagement/service/apiVersionSets', 'foo', 'bar')]"
            }
        }
    ]
}

 The apiVersion 2021-12-01-preview was not found for the resource type: Microsoft.ApiManagement/service/apis 

Neither ARM extension nor bicep complain
