Add a terminal::RerunTask action (#30288)

Bounded this action to the same defaults `task::Rerun` is bound to.

Unlike the `task::Rerun` which will always rerun the latest task, this
command reruns the current task tab, if focused.
The task is not in scope when the terminal pane is not focused, and
falls back to the regular rerun if invoked on a task-less terminal tab.

This way, we can add a proper tooltip to the terminal tab reruns:
