This task involves creating a 3.x branch for the liferay-faces-alloy.git repository and establishing the master branch as 4.x in order to support AlloyUI 3.1, which is the version of AlloyUI used in Liferay Portal 7.3.

It also involves changing usage of the btn-default CSS class name to btn-secondary since btn-default is no longer present in Bootstrap 4, which is the version of Bootstrap used in Liferay Portal 7.3.
