Configure commonmark extensions in twig extra bundle

It is actually possible to include and configure commonmark extensions when using the markdown features of Twig Extra Bundle.

The documentation at https://twig.symfony.com/doc/3.x/filters/markdown_to_html.html does not explain how, so let me show it here.

We need to define a tagged service for the extension and we need to specify the configuration.

⚠️ beware, there is no validation of configuration, neither in Twig Extra Bundle nor in Commonmark that receives the configuration. If your configuration is in the wrong place or has typos, it will simply not be taken into account.

Elasticsearch: Find all documents that have invalid entries in an array

We had a problem where invalid data got stored in elasticsearch. An array of objects had some objects placed in it that are missing a mandatory field. After fixing the mistake, we wanted to update all offending entires. For this, we need to get the IDs of affected items.

The "obvious" query would be _exists_:general_information AND !(_exists_:general_information.value). But as soon as there is any array element with a value, the second condition will consider the value existing. If there are any valid entries in the array, the query will not work as expected.

The solution we found was to use an ES script that loops over the elements in the source document and returns 1 if it finds one that has no data. To our positive surprise, running this on an index with over 1M entries only took a couple of seconds. Definitely not something for a routine query, but an acceptable time for a one-off query to fix a problem.
