Update Shiro spring docs to point to Spring boot by default

We don't have a direct link to the spring-boot page from the menu, The current menu item links to an older XML based approach.
The Spring Boot Page has links to non-boot options (annotations and xml) in the first paragraph, so it make for a better default
