Adding language buttons to the Glossary pages

[LeonieDudda]

On this website https://forrt.org/glossary/german/ (the same holds for the other languages) it is currently not possible to switch between different languages. Currently, the only way to do this is to go to https://forrt.org/glossary/ and select a language. However, as soon as you click on one of these, you cannot switch between languages anymore without going back to the main page. It would be great if the language buttons could be added on these language sub pages as well.
