Include model uri in openVALIDATION responses

[Jaykju]

The openVALIDATION responses that the language-server returns do not contain the model uri.

That means that it is not possible to map the responses to the corresponding model of a monaco editor that contains multiple models.

Sample textDocument/parsingResult:

{
  "jsonrpc": "2.0",
  "method": "textDocument/publishDiagnostics",
  "params": {
    "uri": "inmemory://model/1",
    "diagnostics": []
  }
}

Sample openVALIDATION/parsingResult:

{
  "jsonrpc": "2.0",
  "method": "openVALIDATION/parsingResult",
  "params": {
    "variables": [],
    "diagnostics": [],
    "parsedSchema": {
      "dataProperties": [],
      "complexData": []
    }
  }
}
