attack styles: Attach spec bar redraw listener to weapon text

This fixes a bug where the special attack bar would not be redrawn if
the combat tab was opened with any weapon equipped which did not have a
special attack bar. The weapon text widget is used because it is always
rendered with the combat tab widgets, and does not already have any kind
of listeners attached.

Fixes runelite#8946
