Command is missing from postTasksExecution

[joshlartz]

We're finally getting around to trying out the new API from #29637

What appears to be missing in the conversion from task runners is the command that was run to start off the task graph. I'm specifically looking for command that came from StoreRunInformationLifeCycle and the LifeCycle side of the task runners in general.

The TaskResults typing in the new system is close, but the command is missing. When things like nx run are used, the last item in the task graph is effectively the command that was run, but for nx affected and nx run-many where there are essentially many subgraphs involved, there's no way that I've found to capture the command that started it all.

This is on Nx 20.8 to be clear.

I've implemented this here: #32259

Please try it out in the latest beta: 21.4.0-beta.8+
