XWIKI-14032: The long names of submenus are showing out of the menu box (not wrapped) and the name of the submenus that use plain text and don't have other submenus don't have left margins (#3033)

* Added overflow wrap in words
* Added padding for all items
* Removed unused styles

(cherry picked from commit c17b9bd5)
