Create showcase example of FacesRequestContext

Description

{markdown}
[FacesRequestContext](http://www.liferayfaces.org/doc/faces/4.2/javadoc/util/com/liferay/faces/util/context/FacesRequestContext.html) is documented, but there are no code examples showing how to use it. A showcase example should be added to help teach developers how to use `FacesRequestContext`. The example could take inspiration from [this forum post](https://www.liferay.com/community/forums/-/message_boards/message/62395157) and showcase how to close an `alloy:dialog` once input is valid.
