title: How to remove item from twig cache with it's key
body: <p>I use the twig cache tag in Symfony.</p>
  <p>As described in the <a href="https://twig.symfony.com/doc/3.x/tags/cache.html" rel="nofollow noreferrer">documentation</a>, I use an updatedAt entity property and set the cache tag like this :</p>
  <pre><code>{% &quot;post-&quot; ~ post.id ~ &quot;-&quot; ~ post.updatedAt %}
  </code></pre>
  <p>It's ok to handle post update, category delete or update and comment delete with an eventSubscriber that set a new updatedAt property on the post entity.</p>
  <p>But how can I remove the cached post on post delete ?</p>
