Update django-treebeard dependency to 4.5.1 or above (#7985)

The django-treebeard 4.3.x is not compatible with Django 4.x because of the dreaded ugettext alias removal problem. This makes sure that a proper django-treebeard version will be installed.

*IMPORTANT*: Please notice that django treebeard *does not* officially support django 4.x. However from my tests I have concludeded that it works fine after you install the version 4.5.x.
