parseJson: how to correct use %filepath in the path to errorsRoot

[przepompownia]

Let's see an output of phpstan on some old project:

 $ phpstan analyze --level max --error-format=json php/PHPCD.php         

{

  "files": {

      "messages": [                                                                                                                                                           
        {                                                                                                                                                                     
          "message": "Method PHPCD\\PHPCD::setServer() has no return typehint specified.",                                                                                    
          "line": 100,                                                                                                                                                        
          "ignorable": true                                                                                                                                                   
        }
      ]
    }
  }
}

In the shell the filtering this output by | jq '.files["/home/user/phpcd.vim/php/PHPCD.php"].messages' works.

I tried to make something similar in coc config, e.g. use "errorsRoot": "files[\"%filepath\"].messages" but it does not work. Please update examples with the correct usage if using %filepath in erorsRoot is possible.

I successfully made working equivalent fo phpcs but it can take stdin (phpstan seems to cannot it) and so there is no need to use the filename in the path.
