LPS-41879 On an iPad, tapping outside of dockbar notifications will not close the notifications

Hey @Robert-Frampton,

Here is an update for https://issues.liferay.com/browse/LPS-41879.

I changed the script to use Liferay.MenuToggle for the notification button in the dockbar. This fix does not resolve the problem stated in the ticket directly since it depends on the liferay-menu-toogle module to handle the dropdown. The tapping issue should be fixed when the fix for this ticket https://issues.liferay.com/browse/LPS-44543 is applied. 

P.S. I fixed the alignment issue for the notification icon in this ticket https://issues.liferay.com/browse/LPS-45293.

Please let me know if you have any questions. Thanks!
