Main menu large view - Use light grey to separate menu items (From HE)

For the WET menu

Recommendation: Use a light grey hairline to separate the menu items instead of dark blue
On the examples page a dark blue divider line is used to show the left edge of the clickable area for the “WET project” menu button. The Canada.ca site uses a light grey hairline that separates and defines the edges of the buttons. The light grey line is a better implementation as the contrast of the dark blue divider on a dark blue button bar background is not sufficient. The “Contribute to WET” menu button is also missing the dark blue divider line on the right side that should be there to indicate the edge of the clickable area. (Bug or missing in code?)

Fixed by changing the separator lines to grey.
