OPENEUROPA-2047: Add class for timeline to limit width.

We are wrapping everything around ecl-editor class as both title and long text field should be affected by that. This is not ideal but it will do the job, also considering that the ECL2 upgrade is coming soon.

[voidtek]

The way to handle it is to add a <p class='ecl-paragraph'> for every item.

as we can see in the demo:

<div class="ecl-timeline__body">
  <p class="ecl-paragraph">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer nec tellus congue, pretium nibh eu, mattis ligula. Integer tempus varius enim ut scelerisque. Curabitur rutrum vestibulum elit ac pulvinar.
  </p>
 </div>

After talking with @brummbar we should not do this in the pattern but in the field template.

@voidtek As Anto wrote, we need all elements to be wrapped, title, and body as well. If we would need to wrap individual items that we would need to patch ECL. Since ECLv2 is pending, I advise move as we did for Body and other fields, by wrapping it with ecl-editor class.

[ademarco]

Let's put this on the outside field template instead, it should be like field--....html.twig.

After careful consideration we are back to square one. Approved.
