Set default `hijack` option to true

[phaseOne]

I'm on Docker Desktop for ARM Mac 4.11.1 (84025) and I'm experiencing an issue with dockerode, where writing to stdin never reaches the process in my container.

Based on moby/moby#43799, it seems a change in Docker Desktop 4.10.0 requires that the Connection and Upgrade headers be sent for stream multiplexing to work, since Docker Desktop proxies the docker socket.

I'm not sure if changing this default would be a good idea.

There's a lot of use cases beside Docker Desktop, I would love more opinions on this one.
