[Launch Instance Fix] source step - fix donut chart label color

[Brian Tully]

On the source step of the new Launch Instance Wizard, the label for the donut chart does not match the color in the mockups. The current code uses the "color" attribute to set the label color, but it actually should be the "fill" attribute, as that is what is used by SVG to render the label.
