StepFunction HeartbeatSeconds always times out

[ImerM]

I am aware that this is an example project, but there seems to be an issue with the 2.0.0 version of the state machine template. It uses 'HeartbeatSeconds' when submitting the job to Batch, it's currently set to 60 seconds which is not enough time to provision and turn on a machine so the pipeline fails.

Increasing this to a higher value (for example 600 seconds) also isn't ideal, as while the task is properly submitted and starts running it gets killed by Step Functions, I assume because there is nothing sending it a heartbeat in response. End result is that the pipeline fails each time because of the timeout, so you cannot run the example.
