Create a component to display tree views

[syphax-bouazzouni]

Issue

Currently, we are using Jquery simple tree to display our tree views (for classes/concepts).

And there are multiple issues regarding this:

• The plugin is obsolete
• It is hard to develop new features on it
• We can remove Jquery from our code base (because depend on it)

Requirements

• Create a view component that we will re-implemented using Turbo frames (Zero JS ) or Stimulus JS (like this https://codepen.io/danilonovakovic/pen/bxmWVM)
• Replace the current usage of Jquery simple tree with this new component
• Remove Jquery simple tree
