Examples fail due to the `glossaries` package

Sometime between 2021-09-17 and the latest commit on 2022-12-29, the example documents started failing to compile. I tracked the issue to the glossaries package, which has been part of the examples since fithesis4: Removing the package fixes the compilation problems. Due to the time range, the issue seems to be caused either by release 2022-10-18 of glossaries or by release 2022-11-04.
