[BUGFIX] Render tags of documentation changelog deferred

Currently, when the changelogs get rendered in the Install Tool, for each
document the tags get rendered in the document itself, which has a huge
negative impact on rendering performance.

This patch changes the rendering to the triggered deferred, when the
document is opened.
