Issue running `kiln test` on MacOS due to Docker Desktop socket path

[Gerg]

Describe the bug

Running kiln test doesn't work out of the box on my machine (MacOS + Docker Desktop), due to the location of the docker socket.

Reproduction steps

❯ kiln test --verbose
kiln test: 2023/09/06 19:24:00 connecting to ssh socket "/private/tmp/com.apple.launchd.LRURLkxf4S/Listeners"
kiln test: 2023/09/06 19:24:00 ensuring ssh agent keys are configured
kiln test: 2023/09/06 19:24:00 pinging docker daemon
2023/09/06 19:24:00 could not execute "test": failed to connect to Docker daemon: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Expected behavior

kiln test should run successfully.

Additional context

I was able to work around it by creating a symlink:

❯ sudo ln -s ~/.docker/run/docker.sock /var/run/docker.sock
