Update kasmweb/workspaces to 1.17.0

Would be great if this was upgraded to 1.17.0 with linuxserver.io deprecating their version of docker-in-docker kasm.

I'm currently running kasmweb/workspaces:1.15.0 as indicated in the README and it seems to be working fine

I noticed there was a kasmweb/workspaces:1.16.1 image on dockerhub and tried using it but couldn't get past the installer.

I've used Kasm in a dedicated VM for years and it's amazing! However I've built a beefy single-purpose docker box and would love to move my Kasm VM over to the docker box for a docker only config.

It would be great to see this docker-in-docker image updated regularly with new Kasm releases.

+1 on this. Everything you said I concur with.
