Add 'shift' characters to Quick Accent

### Description of the new feature / enhancement

It would be really helpful if Quick Accent included inverted punctuation on the keys that naturally correspond to them.

For example, the '1' and '!' key should offer '¡' when using the arrow‑key shortcut, and the '/' and '?' key should offer '¿'.

You might implement this as needing to press the shift key, the key on the keyboard, and the arrows or just omit the shift key and have it appear as an option for all the times I press a corresponding key.

### Scenario when this would be used?

I have to write in both Spanish and English, so this change would be useful for easier access to that punctuation, reducing the need for an external keyboard or additional changes to settings.

### Supporting information

_No response_

Start by locating the Quick Accent implementation in PowerToys and review how key mappings and arrow-key options are defined. Confirm the intended interaction for shifted punctuation, then verify that 1/! exposes ¡ and /? exposes ¿ without disrupting existing options.
