LPS-50436 - Migrate Document Library Display portlet aui-base javascript

Hi Rob,

Attached is an update for https://issues.liferay.com/browse/LPS-50436

There is another jsp file in this portlet (select_add_file_entry_type.jsp) that uses aui-base, but I think we need to wait to convert it over.  It is retrieving a node via ```Liferay.SearchContainer.get```,  So I thought we would want to convert that over once we convert 'search_container.js'.

Also, I commented on one line in configuration.jsp where we are referring to a property on a YUI node assigned elsewhere, so I had to leave it alone for now.

Please let me know if there are any issues.

Thanks!
