Fixes #24784: Nodes page has console error from the tree script

https://issues.rudder.io/issues/24784

Within the node details page, the group tree was still having disappearing event handlers (even without the console error) :

• it seems like the previous selectors for tree elements with lift-event-js- id was not applied to the pencils (in the .treeActions container)
• the rendering of the tree only populates event handlers when the ready.jstree event is fired

N.B. : the use case here and the fix here are specific to the node details page, the groups page renders the tree using Elm and does not use the modified code
