upgrade libapache2-mod-qos to the debian trixie version on check-01

after upgrading check-01 (#41252 (closed)), apache broke because of a bug in bookworm's libapache2-mod-qos. the version from trixie is fixed, and according to the debian mailing list it can be used on bookworm https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1000072

i'll be upgrading mod-qos to the trixie version and making sure apache starts on check.
