README.md: rename client.json -> config.json in one place.

I was unlucky to miss all the other references to `config.json` when I was setting up, so I named my file `client.json`, looking instead only at the label changed by this commit. When I later ran a `container_push` target it failed with "permission denied" issues. I read the shell script generated by `container_push` and saw that it passes an argument to give the path to the _directory_ of the config file, rather than the path to the file itself. That made me realize that I had probably given the file the wrong name; the Docker client didn't find a `config.json` file in that directory and ignored all other files.
