Feature request: match command palette icons to navigator icons

[elektronik2k5]

Thanks again for the extension, @MadaraUchiha!

A picture is worth a thousand words:

In the screenshot, it is visible how the .tsx and .story.tsx files lack the icons which are used in tabs and file navigator.
Can we make the palette icons match the other places?

🤔 currently, the icons are emoji ( 📄 and 📁 ), because I'm a lazy bum, but it should be possible to tap into the icon detection of vscode.

vscode-file-navigator/src/extension.ts

Lines 7 to 8 in 8b4df60

	const DIRECTORY_PREFIX = "📁 ";
	const FILE_PREFIX = "📄 ";

If you have the time to investigate it'll be awesome 😄, if not I'll try to get to it in the near future.
