EvaluationFrequency cannot be greater than MuteActionsDuration

### Describe the bug

Running `az monitor scheduled-query create`, specifying `--evaluation-frequency 1h` and _omitting_ `--mute-actions-duration`, returns `EvaluationFrequency cannot be greater than MuteActionsDuration`.

If we do not wish to mute actions for any duration, how could the evaluation frequency ever not be greater than the mute action duration?
