wren-launcher is incompatible with headless linux

[tikimo]

The commands used check for Docker Desktop, which is not in my understanding a requirement.

This prevents the launcher from utilizing a headless Docker installation (Docker CLI) as it keeps looking for the docker-desktop. Docker desktop requires KVM, which is not available on all hosts.

Case:

• Ubuntu 22.04 server, headless, no GUI
• verified that Docker CLI is working

@tikimo thanks for reaching out!

https://github.com/Canner/WrenAI/blob/2d13dddc3c4b146ea2f3afa3b7fe723b834a0b40/wren-launcher/utils/os.go#L57 how about changing the line to "systemctl", "--user", "start", "docker"?

Does that work to you?

works!
