[Unit Frames] Missing UpdateToolitp logic

[Stein-N]

Every UnitFrame is missing a the UpdateTooltip logic.
This prevents any additional modification of the Tooltip by other AddOns.

This can be fixed with the Vanilla UnitFrame_UpdateTooltip function, this inherits the right click line:

Or with this method without the right click line:

local function Custom_UpdateTooltip(frame)
   GameTooltip_SetDefaultAnchor(GameTooltip, frame)
   if GameTooltip:SetUnit(frame.unit) then
      GameTooltip:Show()
      
      frame.UpdateTooltip = Custom_UpdateTooltip
   else
      frame.UpdateTooltip = nil
   end
end
