Schema id not validated as required

[rido-min]

DTDL v2 requires all schema elements to have an id, as reported by the parser:

{
    "@context": "dtmi:dtdl:context;2",
    "@id": "dtmi:test:schemas;1",
    "@type": "Interface",
    "schemas": [
        {
            "@type": "Object",
            "fields": [
                {
                    "name": "rf1",
                    "schema": "integer"
                }
            ]
        }
    ]
}

dtmi:test:schemas;1's property 'schemas' requires an identifer but none provided. Add an '@id' property whose value is a string that conforms to the DTMI syntax -- see https://github.com/Azure/digital-twin-model-identifier.

Current behavior. The Language server does not point this issue
