Add JSP Transformation step

[tbitonti]

Need a rule to transform JSP files, which contain package references. For example, javax.el should be replaced with jakarta.el in the following JSP text:

<%@ page import="com.sun.ts.tests.jsp.common.util.JspTestUtil,
             javax.el.MethodExpression,
             javax.el.MethodInfo,
             javax.el.ELContext"%>
