Uggly Line Highlight on VScode

[ernanvr]

Hi, you've done a great work with your theme extension. I only want to suggest you a change with Line Highlight color.

	"workbench.colorCustomizations": {
		"editor.lineHighlightBackground": "#2e3440",
		"editor.lineHighlightBorder": "#3b4252",
	}

Try it out!
