Add Alt+1, 2, 3, 4, 5 shortcuts for quick selection in PowerToys Run

[Tung-Pro]

Description of the new feature / enhancement

I propose adding keyboard shortcuts Alt+1, Alt+2, Alt+3, Alt+4, Alt+5 to PowerToys Run to allow quick selection of the corresponding search results. This feature will make the tool more efficient for users who rely on keyboard navigation.

Scenario when this would be used?

When a user searches for a command or application in PowerToys Run and wants to quickly execute it without additional navigation.
This feature is particularly useful for power users who prefer keyboard shortcuts for speed and efficiency.

Supporting information

The addition of these shortcuts aligns with common UI patterns, such as using numbered shortcuts in command palettes or search tools.
Similar implementations can be found in tools like Visual Studio Code and IntelliJ IDEA, which also support number-based quick selection.
