[BUGFIX] Remove double escaping in template module

The information of a template (title, site title, description) is
already escaped by using fluid. Therefore the htmlspecialchars() must be
removed in the controller.

This is a fix of the regression of the fluidification of #75031.

Resolves: #79424
Releases: master
