The goal is to define a way of testing BlockNote and Hocuspocus functionality from a unit/integration test perspective.

Currently we face challenges with Hocuspocus, as we don't have it available for rails/capybara. Begin of the insertionP~~lus,End of the insertion Begin of the deletion Plus,End of the deletion we have a challenge with BlockNote now that it is running in a Shadow root. Capybara cannot traverse the **shadow borders** it Begin of the insertionseems.~~End of the insertion Begin of the deletion seems.End of the deletion

So, for this ticket, the plan is:

* Figure out a way of setting up Hocuspocus on the test setup

* Include unit tests to guarantee the base functionality of Hocuspocus and BlockNote
