Bug: Azure ARM/MongodbRoleDefinition response doesn't adhere to schema

[petrepopescu21]

Describe the bug

For the MongodbRoleDefinition API, the schema defines the .properties.type field as an Enum (CustomRole, BuiltInRole), but Azure responds with an int when read via the API

This causes an unmarshaling error, which prevented onboarding the resource in #4550

Azure Service Operator Version: N/A

To Reproduce

az resource show --ids /subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/asotest-rg/providers/Microsoft.DocumentDB/databaseAccounts/asotestdb/mongodbRoleDefinitions/asotest-mongo.dboperator
