treetable.js not loaded correctly due to django.jQuery not defined (js load order)

[erny]

With Django 3.2.15, editor/jquery.treeTable.js seems to be loaded before admin/js/jquery.init.js. (This is caused by django's Media merging algorithm.

To fix it, jQuery and jquery.init must be defined as depedencies. This can be done by prepending them in js list in editor/tree_editor.py:

class Media:
     ...
     extra = '' if django_settings.DEBUG else '.min'
     js = ['admin/js/vendor/jquery/jquery%s.js' % extra, 'admin/js/jquery.init.js', 'editor/jquery.treeTable.js']
