freeswitch entrypoint: de-de-daedalus3 cannot be installed (german audio package)

[yksflip]

With a bbb-docker setup from main branch the german sound files won't work, as unzip is not available.

Steps to reproduce:

1. select german sound files in .env: SOUNDS_LANGUAGE=de-de-daedalus3
2. ./scripts/generate-compose
3. docker compose up
4. see bbb-freeswitch | /entrypoint.sh: line 35: unzip: command not found

I thought it might be easy to fix by adding zip to the apt-get install statement in mod/freeswitch/Dockerfile:48, but when running docker compose build the stage failed, because the package server cannot be reached?!
