Docker - Docker mod for code-server

This mod adds docker and docker-compose binaries to code-server.

IMPORTANT NOTE: For docker access inside code-server, a volume mapping needs to be added for /var/run/docker.sock:/var/run/docker.sock in code-server docker run/create/compose.

In code-server docker arguments, set an environment variable DOCKER_MODS=linuxserver/mods:code-server-docker to enable.

If adding multiple mods, enter them in an array separated by |, such as DOCKER_MODS=linuxserver/mods:code-server-docker|linuxserver/mods:code-server-mod2
