LPS-51142 Web Content Configuration setting are all on the same line

Hey Hugo.

A fix for https://issues.liferay.com/browse/LPS-51142.

The <aui:field-wrapper> will apply css display:inline-block which makes all the input in one line.

Just remove the <aui:field-wrapper> to make it following the configuration.jsp in other portlet.

Let me know if you have any concerns.

John.
