title: Get version from composer.json [Symfony]
body: <p>I wonder if there is a way to get the <code>composer.json</code> version from a controller with Symfony. My <code>composer.json</code> looks like:</p>
  
  <pre><code>{
      "name": "myProject",
      "version": "0.0.0",
      "description": "myProject description",
      "license": "AGPL-3.0",
      "type": "project",
      "require": {
          "php": "^7.1.3",
          ...
      }
  }
  </code></pre>
  
  <p>I can't find any reference to this.</p>
  
  <p>PS: I'm using Symfony 4.</p>
