Use blade gw formatSource command to format source code into Liferay standards.

A few new comments related to this issue:

• I've noticed there is a collection json file within the project root folder and other two within postman folder. @afablf said that you guys are using the Liferay.postman_collection file. So, should we delete the other two files to avoid unused files inside our project?
• Also, I was passing through the project modules and I suggest to create a exception subpackage for ApiResponseException class inside liferay-sample-module-ws-client/src/main/java/com/liferay/sample/module/ws/api directory to better organization of source code.
