Inlay hints

[rqbik]

Describe what you want
With VSCode's August update, there is now an option for enabling inlay hints — boxes with additional type information. It would be very nice to have them properly colored:

(I'm using One Dark Pro Darker theme in the screenshot)

Additional context
For anyone not willing to wait until the theme fix, you can overwrite hints' style in your settings.json:

"workbench.colorCustomizations": {
	"[One Dark Pro Darker]": {
	    "editorInlayHint.foreground": "#abb2bf",
	    "editorInlayHint.background": "#2c313c"
	}
}
