Wiki syntax false formatted

When entering valid syntax in the OpenOlat wiki the resulted formatting is wrong.

E.g.:

=level 1=
==level 2==
===level 3===
====level 4====
=====level 5=====
======level 6======

Only part of the syntax is displayed correctly and the sizes do not render as expected.

--------

Unfortunately OpenOLAT uses an older jamwiki version which only supports 5 levels. It is not possible to update without rebuilding more or less the entire wiki. So, this is not an option.

For the moment only 5 levels are supported. But the wrong rendering of the first five levels can be fixed.
