new typeface for quick accent character selector

### Description of the new feature / enhancement

change the quick accent typeface to one where pairs such as `“`/`”` or `‘`/`’` are easily distinguishable, or add the option to change that typeface｡

### Scenario when this would be used?

even with the unicode names displayed, it would be quicker to distinguish them if the characters were more visually distinct, since you have to first preselect a character before its name is displayed｡

### Supporting information

_No response_

No file or test is named. Start by locating the PowerToys quick accent character selector and its current typeface and Unicode-name display; done means paired quotation characters are visibly distinguishable, or the selector provides a usable typeface option, with the behavior checked in the selector.
