App Platform: Default value is invalid for temporaryDisk

[mikhailshilkov]

In the latest 2020-07-01 API version, the temporaryDisk property defines a default value "/tmp":

azure-rest-api-specs/specification/appplatform/resource-manager/Microsoft.AppPlatform/stable/2020-07-01/appplatform.json

Lines 3420 to 3423 in f15b4f3

	"temporaryDisk": {
	"$ref": "#/definitions/TemporaryDisk",
	"description": "Temporary disk settings",
	"default": "/tmp"

This is wrong because temporaryDisk is an object of type TemporaryDisk with a property mountPath. It's the property that should have the default value.

The issue is introduced in #13927
