feat: Allow to access Site template through a dedicated Web Handler - M…

…EED-7669 - Meeds-io/MIPs#165 (#2532)

This change will allow to access the group site template through a
dedicated URL in order to allow displaying portlets added into it. This
is a temporary Handler that will be changed once WebUI is cleaned up to
rely on Portlet container directly instead.
