Fix docker run command in autostart script example

[tedwardd]

The command as currently shown in the example does not work. Hummingbot crashes without a pseudo-TTY. Adding -t at a minimum fixes this. Adding -i to keep STDIN open, even when the container is detached, seems like a good idea as well, though it may not be required. Including it does not seem to cause any problems.
