Avoid using a / in a web module welcome file name

This rule flags any web module <welcome-file> that starts with a forward slash character (/) or a back slash character (\) in the web.xml file.

The automated fix will remove the / or the \ from the name.

Given the following welcome file list:
<welcome-file-list>
<welcome-file>/index.html</welcome-file>
<welcome-file>\index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>/default.html</welcome-file>
<welcome-file>\default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>

The automated fix will update four entries of the code to:
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
<welcome-file>default.html</welcome-file>
<welcome-file>default.htm</welcome-file>
<welcome-file>default.jsp</welcome-file>
</welcome-file-list>
