Linux dependency installation

[poetaman]

As of writing this, GitHub doesn't allow PRs for wiki pages of repositories. You are welcome to leave your Linux distro-specific installation commands for arttime's dependencies here. Create a bullet list like for Debian below (Unix has its own discussion page: Unix dependency installation). It might also get echoed on arttime wiki.

### Debian
* ``zsh``: ``apt install zsh``
* ``vorbis-tools``: ``apt install vorbis-tools`` (not strictly needed as pulseaudio is preinstalled, though recommend as a fallback to have anyway)
* ``notify-send``: ``apt install libnotify-bin``
