new undo report not human readable

[Andonome]

On version 3.0.0, I did task undo, which produces this:

The following 8 operations would be reverted:
- Update 90f0b9d3-9ed7-4919-933a-1f3748b1829f
    status: <empty> -> pending

    scheduled: <empty> -> 1713340800

- Create 90f0b9d3-9ed7-4919-933a-1f3748b1829f
The undo command is not reversible.  Are you sure you want to revert to theyesevious state? (yes/no) 

This is a surprising amount of feedback for 'undo last change'. Of course it's all true, but I feel that the previous behaviour gave more meaningful output.

I've changed the description to 'raise taskwarrior issue'.
