FAIL contrast on focused + selected .treeViewAppendageColumn element

[nchevobbe]

When a line is selected, the path to the file has a contrast of 2.9:1, which is not accessible

That's caused by the opacity: 0.6 in

profiler/src/components/shared/TreeView.css

Lines 150 to 153 in 61a5894

	.treeViewAppendageColumn {
	margin-left: 10px;
	opacity: 0.6;
	}

I find it easier to redefine the color than setting lower opacity, as it's harder to exactly know how the different colors are going to play together
