add an "alternative key" for ”Direct activation command“ option of Powertoys Run

### Description of the new feature / enhancement

There's the common issue for "half-width" and "full-width" characters in all of east asian...

So. using Powertoys Run to execute a plugin, type a ”Direct activation command“, such as `< > ( )`. if no changed the current input method (e.g. "pinyin"), the input char will be "full-width" `《 ` instead of "half-width" `<`

Can add multiple ”Direct activation command“ (alternative key?) to increase the kind of input chars?

### Scenario when this would be used?

### Supporting information

_No response_

The issue does not name files, tests, or an implementation entry point. Start by locating PowerToys Run's handling of the “Direct activation command” option and determine how multiple alternative keys should be configured; done means plugins can be activated with the intended half-width and full-width input variants.
